AudioQuest DragonFly Red Portable Headphone Amplifier & USB DAC at 1627.00 HKD from TREOO.com
AudioQuest DragonFly Red Portable Headphone Amplifier & USB DAC
HK$ 1,627.00
The Original DragonFly Launched in 2012, press and public alike have enthusiastically embraced AudioQuest’s multi-award-winning DragonFly USB digital-to-analog converter/preamp/headphone amp as the rare audio product that bridges the gap between die-hard audiophiles and mainstream music lovers. DragonFly plugs into a computer’s USB port to bypass the computer’s compromised audio circuitry and deliver cleaner, clearer, more naturally beautiful sound to headphones, powered speakers, and complete audio systems. Small, affordable, easy to use, and remarkably effective, DragonFly was named Stereophile’s 2012 “Computer Audio Component of the Year” and 2012 “Budget Component of the Year;” Tone Audio’s 2012 “Digital Product of the Year;” Computer Audiophile’s 2012 “Computer Audiophile Product of the Year;” AudioStream’s “Greatest Bits;” and What Hi-Fi?’s 2014 “Product of the Year.” Perhaps most memorably, DigitalAudioReview.net’s John Darko quipped: “A DAC with the DragonFly’s performance at the DragonFly’s price point is as rare as rocking horse sh*t.” We couldn’t have said it better. The Next Generation: DragonFly Black & DragonFly Red While the original DragonFly defined the market for micro-DACs, its USB power draw made it compatible with computers only. Music lovers have craved a more portable version—one that could be reliably used with Apple and Android smartphones and tablets. We’re delighted to present two new options that do just that: DragonFly Black and DragonFly Red. Convenience and performance are no longer mutually exclusive. With DragonFly Black and Red, any computer, laptop, tablet, or smartphone can be used as a true high-fidelity music player, allowing music lovers to enjoy beautiful sound wherever they go, whenever they please. AudioQuest, Gordon Rankin, and Microchip: A Beautiful Partnership AudioQuest and DragonFly designer Gordon Rankin worked alongside Microchip Technology to develop a new high-performance, full-speed USB microcontroller solution that delivers improved signal-to-noise ratio and significantly lower power consumption. Drawing 77% less current than the previous microcontroller, the new Microchip Pic32Mx microcontroller enables true compatibility with Apple and Android smartphones and tablets. Further, we simply cannot overstate the significance of Gordon Rankin’s contributions to AudioQuest. The new DragonFly models embody many of Gordon’s most innovative, creative, and elegant digital-audio solutions to date. Improved 32-Bit Digital Performance For greater overall performance, the new DragonFly models also incorporate improved 32-bit ESS Sabre DAC chips—the 9010 in Black and the higher-performance 9016 in Red—both of which employ minimum-phase filtering for naturally detailed, more authentic sound. While DragonFly Black uses the same high-quality headphone amp and analog volume control found in DragonFly v1.2, DragonFly Red includes the latest ESS headphone amp and a bit-perfect digital volume control that resides on the 9016 DAC chip itself—a sophisticated implementation that ensures maximum fidelity, dynamic contrast, and signal-to-noise ratio. DragonFly Black will output 1.2 volts—enough power to successfully drive all preamplifier input circuits and a wide range of today’s efficient headphones. Meanwhile, with its higher 2.1-volt output, DragonFly Red will be compatible with a wider range of headphones, including power-hungry, low-efficiency models. While the DAC chips we’ve selected are remarkably powerful and sophisticated, we’ve intentionally limited DragonFly Black and DragonFly Red’s processing capabilities to 24-bit/96kHz resolution. This makes using the DragonFlys as simple as it’s always been: they’re fully compatible with PCs without having to download and install new drivers. Most importantly, DragonFly is designed to honor the music you already own and love. Whether you’re listening to Spotify, YouTube, Tidal, ripped CDs, or state-of-the-art high-resolution files, DragonFly will deliver a more emotionally compelling and enjoyable experience. Free Desktop Application for Software Upgradability (for DragonFly Black and Red only) In addition, the new DragonFlys will be software upgradeable through a complimentary Windows or OS X desktop application. As new developments arise in music player applications, streaming protocols, or other associated software, DragonFly users will be able to incorporate those updates to their existing devices. Only the Beginning Introduced to the media at the 2016 Consumer Electronics Show, DragonFly Black and DragonFly Red were named “Stars of Ces” by What Hi-Fi? Magazine. But this is only the beginning. We look forward to building stronger, more meaningful connections between music enthusiasts and the artists, albums, songs, and videos they love. Our hope is that with DragonFly Black, DragonFly Red, and future AudioQuest digital products, more people than ever before can enjoy beautiful music—wherever they go, whenever they please.

OPPO Ha-2Se Portable Headphone Amplifier and USB DAC at 2607.00 HKD from TREOO.com
OPPO Ha-2Se Portable Headphone Amplifier and USB DAC
HK$ 2,607.00
High-Resolution Audio Meets Style and Design Ha-2Se is an elegant yet sophisticated portable headphone amplifier with a built-in rechargeable battery. It is engineered to enhance music playback from mobile phones and portable music players. Its genuine leather casing with contrast stitching and beveled aluminium edges are eye-catching. It can be used to charge mobile devices conveniently on-the-go, and itself can be efficiently topped-up in 30 minutes. High Performance Audio Hybrid Class AB Amplifier The HA-2SE's power amplification circuit for the headphones is Class AB built with integrated circuits (ICs) and discrete transistors. The discrete transistor output stage uses hand-picked and matched parts. The output transistors are biased to operate in their most linear range for the critical small signal, and deliver their full potential when power is required. Clean Signal Path There is no DSP (Digital Signal Processor) in the Ha-2Se. Volume control is operated by a combination of the DAC chip's internal digital volume control and an analog potentiometer (the familiar volume knob). Bass boost is performed by pure analog audio circuits. By avoiding re-digitizing the audio signal for volume adjustment or bass boost, the Ha-2Se provides a clean signal path for the audio. Audio-In and Line-Out The Ha-2Se has a 3.5 mm Audio-In port to support portable music players that do not have a USB-compatible digital output. While the Ha-2Se is used with one of its USB digital input ports, the 3.5 mm jack acts as Line-Out for the USB Dac. ESS Sabre32 Reference DAC The DAC is one of the most important components for digital audio playback. The Es9028-Q2M DAC chip used in the Ha-2Se is the latest flagship mobile DAC developed by ESS Technology. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the Sabre32 Reference DAC delivers an unprecedented performance for mobile applications. Asynchronous USB DAC By bypassing the smartphone's built-in DAC and headphone amplification circuit that are often cost-constrained, the Ha-2Se turns a smartphone into a high performance digital audio player. The asynchronous USB DAC input of the Ha-2Se also works with PC and Mac computers to replace the built-in sound card and support high-resolution audio playback with PCM up to 384 kHz 32-bit and DSD up to 12 MHz (Dsd256). Bass Boost For those who like a bit more punch and impact with their music, the Ha-2Se offers a Bass Boost function. With Bass Boost off, the Ha-2Se delivers a ruler-flat frequency response; with Bass Boost on, the Ha-2Se adds force and impact to the sub-bass region without muddling the important mid- to high-frequency bands. Two Gain Settings The Ha-2Se offers two gain level settings for optimal headphone matching. The High Gain mode is capable of driving large power-hungry headphones, delivering up to 300 mW into 16-Ohm headphones. The Low Gain mode is intended for sensitive In-Ear Monitor type earphones. Premium Mobility Made for iPod®; iPhone® and iPad® The Ha-2Se passes Apple's "MFi" certification and is compatible with the latest iPod, iPhone and iPad to be used as the digital audio output accessory of these devices. By tapping directly into the digital audio signal of these devices and converting the audio to analog using the high performance Sabre32 Reference Dac, music from your favorite portable device will sound its best. Furthermore, for users with high-resolution music playback apps, the Ha-2Se does not require the use of a Camera Connection Kit (Cck). The data cables that come with your Apple device or the supplied Lightning cable is sufficient. Compatible with Android The HA-2SE’s micro-USB input port works with Android devices that support USB OTG (Usb On-The-Go) and USB Audio Class. A special USB OTG cable is supplied with the Ha-2Se to facilitate the connection. When used with a compatible Android device, the Ha-2Se can support the device's built-in music app, tones and notifications. Additionally, a high-resolution music playback app can use the Ha-2Se as its external DAC to play lossless PCM and DSD audio files. Mobile Power Bank The Ha-2Se functions as an external battery pack to charge your mobile device. Utility and convenience are factors we wanted to address with the Ha-2Se, so you can ditch the bulky spare battery pack and carry just the Ha-2Se with you mobile phone. Rapid Charging The Ha-2Se features patented Vooc rapid charging technology from Oppo. Using the supplied rapid charger, the internal battery can be quickly and safely charged to 70% capacity in about 30 minutes. It only takes approximately 90 minutes to fully charge the battery. A quick charge gives the Ha-2Se hours of operation time. Build Quality The Ha-2Se is housed in an aluminum chassis wrapped in genuine leather. The beveled metal edges and contrast stitching on the leather are eye-catching. Its fit and finish will instill a sense of pride when using the product. The Ha-2Se meshes equally well in the pocket of an urban Millennial or on the desk of a business executive.

 Schiit Audio Vali 2 Desktop Headphone Amplifier at 1627.00 HKD from TREOO.com
Schiit Audio Vali 2 Desktop Headphone Amplifier
HK$ 1,627.00
Welcome to the most affordable serious tube hybrid amp on the planet—with performance and versatility that eclipse amps costing much, much more. The all-new Vali 2 is a great way to get started with tube sound, without needing a second mortgage! The Most Serious Tube Design—Far Beyond its Price Some inexpensive (and not-so-inexpensive) tube amps don’t use tubes to their full potential, “starving” them with low plate voltages or using op-amp buffers for output. Not Vali 2. Vali 2 uses a unique, class-leading power supply that gives us 60V on the plate. Combined with a fully discrete, current-mode noninverting hybrid topology, Vali 2 redefines what you can expect from an affordable tube amp, even at 2x its price. Roll Your Own Sound Vali 2 is supplied with a single NOS 6Bz7 tube, which can be swapped for the same tubes we use in Lyr 2 and Mjolnir 2—feel free to use virtually any Ecc88, 6922, 6Dj8, 2492, etc to “roll” the sound to your own preference. Plus, you only need a single tube, so rolling is easy and more affordable! Serious Power, Gain Switching, Preamp Outputs Vali delivers 1W into 32 ohms for hard-to-drive headphones—and; at the same time, offers a low gain mode for low-noise performance with sensitive headphones. You can also use the preamp outputs to add a tube preamp to your power amp or powered monitors. Made in Usa. Really. By “made in Usa;” we mean made in Usa. The vast majority of the total production cost of Vali 2—chassis; boards, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley. Yep, the wall wart is from China, but there you go. There is some give and take to reach this price point.

FiiO E09K Qogir Desktop Headphone Amplifier at 974.00 HKD from TREOO.com
FiiO E09K Qogir Desktop Headphone Amplifier
HK$ 974.00
The FiiO E09K Desktop Headphone Amplifier with E17 Dock In is designed to work with the FiiO E7, E07K and the E17. It features dual-channel power outputs for both 1/4" and 1/8" headphone plugs, as well as an additional RCA L/R audio output, USB interface and line input. The amplifier features a Texas Instruments main power amp integrated circuit with a low noise level, low distortion and a high conversion rate. The E09K is cleverly designed with an E17 dock for using the line out signal from the Fiio E17 docking port. This provides better sound quality and makes the amp able to drive high impedance or low sensitivity headphones -- giving you the clarity and punch to make your music sound alive and vibrant. Plus, it lets you charge and sync the E17 with your computer as well. The E09K even has a Low/High gain section switch, LED power indicator and a built-in power converter to meet the demands of high dynamic signal processing. Based on the FiiO E9, this updated version allows for synchronously working for power supply and turn on/off. When using with E17, it only needs to turn on/off E09K, and E17 will turn on/off at the same time. When selecting AUX IN and Dock IN signal of E09K, there is no need to take out Dock from E17, you just need to adjust the switch. The Eo9K features reliable, durable RCA gold-plated terminals rather than 3.5mm connectors. Other than these updates, there is no tone quality difference between FiiO's E09K and earlier E9. Note: The FiiO E09K is the newest batch which does NOT have compatibility issues with the FiiO E7 as it may have been stated in some product reviews of the E09K.

Icon NuForce iDo Portable Headphone Amplifier & USB DAC - Silver
HK$ 2,095.00
NuForce Icon iDo is an Audiophile-Grade DAC and Headphone Amp for iPad®; iPhone® and iPod Touch®. iDo extracts audio data in its original digital form (in USB Host mode) from Apple mobile digital devices, delivering bit-perfect, low-jitter, audiophile-quality music file playback. The Icon iDo delivers audiophile-grade CD quality sound to digital music files stored on Apple® mobile digital devices. iDo is ideal for music enthusiasts and musicians alike who primarily listen to—and have their digital music libraries stored on—these devices. Apple products are becoming the hub of a person’s entire music and audio collection, so improving the audio quality produced by these devices is key. The Icon iDo delivers on that at very affordable price point. A fast and easy connection. Using the Icon iDo is simple. Users can connect any Apple mobile device to the Icon iDo with the Apple® approved and included 30-pin sync/charging cable, attach the power supply, and then plug the Icon iDo into a home stereo system using RCA cables or a single coaxial. Users can also plug in headphones directly into the Icon iDo for personal high quality sound playback in a manner the artist intended it to be heard. How iDo makes music stored on Apple devices sound even better? Apple uses its own audio codec, Apple Lossless Encoder (Ale), to compress and store music files on its devices in original CD quality without loss. However, even ALE files only sound as good as the default DAC (digital-to-analog converter) found within the mobile digital device. Icon iDo bypasses the built-in DAC and extracts the audio data stored on the device in its original digital form in USB Host Mode. It then converts the high-quality files for bit-perfect and low-jitter music playback. A portable power station for the ultimate headphone listening experience. Icon iDo also offers a built-in headphone amplifier capable of powering power-hungry headsets, giving users a total audio experience. By properly powering headphones, Icon iDo enhances the auditory performance of the headphones because optimal amperage is being delivered to them, allowing for greater audio clarity. *The maximum sample rate currently supported by Apple is 16-bit/44.1kHz or 24-bit/48kHz. **Icon iDo is designed to work with Apple iTune and iPod software. Other applications may not work (but we have not found any application that is incompatible with iDo).

NuForce Mobile Music Pump Portable Headphone Amplifier - Black at 430.00 HKD from TREOO.com
NuForce Mobile Music Pump Portable Headphone Amplifier - Black
HK$ 430.00
The NuForce Mobile Music Pump (Mmp) is a portable headphone amplifier designed to make your music truly come alive… wherever you go. The fact is that the majority of hand-held audio playback devices simply aren't capable of adequately powering many of today's quality headphones. This is because headphones present a definite challenge to amplifier designers. There are two basic types: the Over-Ear (Oe) in general use in the recording industry, and the smaller In-Ear (Ie), a.k.a. "ear-bud" type commonly used with portable devices such as MP3 players. Given the range of available OE and IE headphones, in attempting to accommodate them all, your mobile device’s headphone output is optimized for none. Typically, OE types exhibit sensitivities of about 100dB/mW, whereas IE devices can be 10dB higher or more, e.g., 110dB/mW. Assuming a 10dB difference, the lower sensitivity OE headphones require ten times more power to achieve the same volume as the IE type. If you’re using OE headphones, you’ll really appreciate the NuForce MMP power capability. Your headphones will sound distinctly clearer and more natural. Just connect the MMP to the headphone output of your MP3 player, Smartphone, iDevice, etc. and finally start experiencing the higher level of performance your headphones were always capable of.

Icon NuForce uDAC-2SE Portable Headphone Amplifier & USB DAC - Special Edition Red
HK$ 1,959.00
Advanced NuForce technology delivers highest-resolution audio for superior sound. If you own a laptop and love music, you need a NuForce uDAC-2SE. If you're a gamer, uDAC-2SE brings realistic sound effects that put you in the game. The NuForce uDAC-2SE is a high-performance, 24bit/96kHz USB Digital Audio Converter (Dac) that connects your personal computer's audio to your home stereo, desktop sound system, or headphones to deliver superior sound. It improves upon our original uDAC model by providing a highly linear Tocos volume control for improved channel tracking at low listening levels, a 24bit/96kHz USB Dac, and an improved headphone amp. Powerful sound in a small, affordable package. Don't let its diminutive size fool you: the uDAC family packs a proverbial punch when it comes to improving the sound you get from your computer, meeting or exceeding the performance of audiophile-grade CD players. uDAC is also flexible: its outputs include analog Rca, digital coaxial, and high-performance headphone outputs to accommodate most computers and self-powering headphones. Why the little uDAC can make such a big difference. The DAC (Digital Audio Converter) in most laptops are typically not designed to deliver best-quality sound. This can result in subtle errors in the rebuilding process, diminishing audio quality. Advanced NuForce DACs create a warmer, more detailed approximation of the source file. Audio sounds richer and fuller, with more clarity on the high and and more depth and power in the mids and lows. You'll hear details in your favorite music you never heard before. Your favorite headphones and speakers reproduce sound to their full potential. About Asynchronous USB Audio The uDAC-2SE (Special Edition) and uDAC-2SGE (Signature Gold Edition) are designed for Asynchronous USB Audio mode. The difference between synchronous and asynchronous USB audio is detectable by most, but best left for the individual audio enthusiast and audiophile to decide. That's why if you're new to appreciating high-quality USB audio, we recommend that you start with our baseline uDAC-2 model without Asynchronous USB Audio to avoid the more involved setup required for AA. If you ever decide to upgrade to a uDAC-2SE, we provide the option to purchase a kit (Sgd $189) that includes a replacement circuit board and stainless steel front and back panels* *For more information, please refer to the Async USB Audio FAQ and Setup Guide. No matter what uDAC you choose to start with, you can expect to hear detail, warmth and clarity from your computer's digital audio files you've never heard before. On listening at low volumes: If you're using the uDAC-2 with sensitive in-ear earphones and listening at low volume, please read this article about channel imbalance issues . Notes For Recording Engineer: The uDAC-2 is designed for consumer playback of digital music and has not been calibrated for professional recording. At the 9 o'clock volume indicator, there is hardly any signal; further, analog pots do not behave reliably. At normal listening levels, the volume tracking is within 1dB. The uDAC-2 volume maxes out at around 0dB input (maximum digital input). Thd+N around 1% is intentional to target the voltage rail limit in order to achieve the loudest possible, but distortionless, music playback. Short of 1% THD at 0dB input, the Dac2 is not at its voltage limit, which results in diminished volume for music.

Applications such as the volume can be precisely and infinitely adjusted via the convenient remote control. As a special highlight, the A2 is currently the only device on the market that provides separate adjustments for the impedance and sensitivity of the connected headphones as well as different levels of the audio sources. This means that headphones between 16 ohms and 600 ohms can be operated perfectly on the A 2 without distortion occurring at high levels. With the voltage selector switch the supply voltage can be adjusted to 110 - 120 V or 220 - 240 V, which allows the device to be used worldwide. Sophisticated Industrial Design Like its little brother, the A 20, the A 2 top-of-the-line model is based on a clearly structured, elegant design with smooth rounded housing edges without visible joints, screws or rivets made of anodised aluminium. Another special eye-catcher is the transparent charcoal-coloured glass panel, which is flush with the top surface, enabling you to look through the famous beyerdynamic sound-wave logo into the interior of the A2. LEDs spectacularly illuminate the circuit board in a warm light. Each A 2 is supplied with an extraordinary accessory, a rugged headphone stand made of aluminium. When it is attached to the device, it serves as a practical storage solution for the headphone keeping it ready at all times hanging over the device.

The successful preorders have approved the acceptance of this wonderful amplifier! The Rendition 1 is an exciting portable amp, that in keeping with Heir Audio tradition, sounds as good as it looks, and looks as good as it sounds. The sound quality can be described as “black” (quite) or without back ground hiss. The concept behind the amp was to add more “depth” and “control” to the music, rather than adding colouration. If bass is present in the music, the amp is there, waiting to add more depth; if there are highs in the music, the amp delivers those as well cleanly and clearly. The Rendition 1 is available in two case colours, black or silver, accented with black carbon fiber, rendering a look of unsurpassed class.

JDS Labs Objective2 Desktop Headphone Amplifier - Silver
HK$ 1,138.00
The Objective2 (O2) is an open source headphone amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost. This item includes a fully assembled and hand tested O2 amplifier, ready for use. You will only need an AC adapter suitable for your region. The O2 has created a stir in Head-Fi.org’s do-it-yourself community. After being banned from Head-Fi for heated discussion, he proceeded to design O2 for maximum benchmark performance to prove his points. It’s large and heavy, so hardly worth consideration as a portable amp, however, O2 lives up to its name. For more information on the O2, please refer to NwAvGuy's O2 Details article. Note: You need a separate power adapter with this device. If you do not have one, please add the G.e.z. 15Vac Power Adapter to cart. Customisation The default gain levels of the Objective2 are intended to work well with over 95% of headphones on the market. We use the stock O2 with headphones as low as 16 ohms @ 108 dB/mW, and as high as 600 ohms (very high and very low efficiency, respectively). There is no reason to change the stock gain unless you regularly listen at extremely low volumes. Gain can easily be changed by removing two resistors. You may choose for JDS Labs to set gain of 1.0x/6.5x or 2.5x/1.0x, and such customisations will only be on pre-order basis (2-3 weeks).

Icon NuForce uDAC-2 Portable Headphone Amplifier & USB DAC - Black

Advanced NuForce technology delivers highest-resolution audio for superior sound. If you own a laptop and love music, you need a NuForce uDAC-2. If you're a gamer, uDAC-2 brings realistic sound effects that put you in the game. The NuForce uDAC-2 is a high-performance, 24bit/96kHz USB Digital Audio Converter (Dac) that connects your personal computer's audio to your home stereo, desktop sound system, or headphones to deliver superior sound. It improves upon our original uDAC model by providing a highly linear Tocos volume control for improved channel tracking at low listening levels, a 24bit/96kHz USB Dac, and an improved headphone amp. Powerful sound in a small, affordable package. Don't let its diminutive size fool you: the uDAC family packs a proverbial punch when it comes to improving the sound you get from your computer, meeting or exceeding the performance of audiophile-grade CD players. uDAC is also flexible: its outputs include analog Rca, digital coaxial, and high-performance headphone outputs to accommodate most computers and self-powering headphones. Why the little uDAC can make such a big difference. The DAC (Digital Audio Converter) in most laptops are typically not designed to deliver best-quality sound. This can result in subtle errors in the rebuilding process, diminishing audio quality. Advanced NuForce DACs create a warmer, more detailed approximation of the source file. Audio sounds richer and fuller, with more clarity on the high and and more depth and power in the mids and lows. You'll hear details in your favorite music you never heard before. Your favorite headphones and speakers reproduce sound to their full potential. About Asynchronous USB Audio Only the uDAC-2SE (Special Edition) and uDAC-2SGE (Signature Gold Edition) are designed for Asynchronous USB Audio mode. The difference between synchronous and asynchronous USB audio is detectable by most, but best left for the individual audio enthusiast and audiophile to decide. That's why if you're new to appreciating high-quality USB audio, we recommend that you start with our baseline uDAC-2 model without Asynchronous USB Audio to avoid the more involved setup required for AA. If you ever decide to upgrade to a uDAC-2SE, we provide the option to purchase a kit (Sgd $189) that includes a replacement circuit board and stainless steel front and back panels* *For more information, please refer to the Async USB Audio FAQ and Setup Guide. No matter what uDAC you choose to start with, you can expect to hear detail, warmth and clarity from your computer's digital audio files you've never heard before. On listening at low volumes: If you're using the uDAC-2 with sensitive in-ear earphones and listening at low volume, please read this article about channel imbalance issues . Notes For Recording Engineer: The uDAC-2 is designed for consumer playback of digital music and has not been calibrated for professional recording. At the 9 o'clock volume indicator, there is hardly any signal; further, analog pots do not behave reliably. At normal listening levels, the volume tracking is within 1dB. The uDAC-2 volume maxes out at around 0dB input (maximum digital input). Thd+N around 1% is intentional to target the voltage rail limit in order to achieve the loudest possible, but distortionless, music playback. Short of 1% THD at 0dB input, the Dac2 is not at its voltage limit, which results in diminished volume for music.

 JDS Labs CMoyBB v2.03 Portable Headphone Amplifier (Demo Unit) at 681.00 HKD from TREOO.com
JDS Labs CMoyBB v2.03 Portable Headphone Amplifier (Demo Unit)
HK$ 681.00
Exclusive Bass Boost Switch The cMoyBB ships with an internal bass boost toggle switch. Switched off, the original, flat audio signal is amplified. Switched on, bass is increased up to 9.4 dB, just shy of a perceived 2x increase in bass volume. Do-it-yourself builders have the option to substitute the bass boost toggle switch for a bass boost control knob. Printed Circuit Board (Pcb) Most cMoys are built on protoboard and use thin wires to transfer the audio signal, making them prone to interference and signal degradation. The cMoyBB v2.03 uses a top-layer ground plane and tightly optimized signal traces, easily outperforming hand-soldered protoboard connections. Proprietary software was used during design of the PCB to check for proper impedance characteristics and negligible crosstalk. Such attention to detail cannot be achieved in protoboard amplifiers, or even in circuit boards designed by most hobbyists. Not sure what all of this means? Check out the cMoyBB reviews. Power System A Texas Instruments Tle2426 precision rail splitter and 25V, low noise Nichicon 470 uF capacitor are used to eliminate the unbalanced resistor divider power system found in standard cMoys. The cMoyBB handles more than double the voltage of most cMoys, meaning the dynamic range of high impedance headphones can be extended even further when using a high voltage DC adapter. Version 2.03 optionally allows for a second Tle2426 rail splitter, giving the cMoyBB more current handling capability than ever! The cMoyBB v2.03 also employs ceramic decoupling capacitors on all IC power pins. Decoupling helps to prevent IC supply ringing, which significantly enhances opamp stability and sound quality. DC Auxiliary Power Input Jack Any regulated 9-24V DC power adapter with a 1.3mm x 3.5mm DC jack can be used to power the cMoyBB amplifier. Connecting a DC power adapter to a non-rechargeable cMoyBB automatically and safely disconnects the 9V battery. cMoyBBs equipped with NiMH recharging circuitry use the same jack to charge the battery. The cMoyBB can be used while charging! JDS Labs does not sell or include Ac/dc adapters. However, a DC adapter can be purchased for as little as $10 (Usd) in North America. See Instructions for details. Enclosure The cMoyBB v2.03 is cased inside of a brand new* Altoids® Peppermint tin, protecting the circuit from some forms of external EMI / RF interference. Foam support keeps the battery securely in place. Other mint tins are sometimes in stock. Contact us if you have something specific in mind. *Despite each tin being brand new, Altoids ® tins occasionally have some sort of scratch or dent (not always!). Additionally, you should anticipate minor jack mounting imperfections due to the hand built nature of the product. Please excuse these possible minor cosmetic defects. Options: In addition to gain adjustment, the cMoyBB can be assembled in four ways: Standard, Non-rechargeable, 1x9V battery. Best for most users. External DC jack can be used to power the amplifier; does not charge battery. Standard, Non-rechargeable, 2x9V batteries (18V). Recommended for high volume listening with 120+ ohm headphones. Rechargeable, 1x9 battery. Ideal for portable use of most headphones. Includes 1x9V Tenergy low self-discharge NiMH battery. Requires a 10V+ Ac/dc adapter (not included)! Rechargeable, 2x9 batteries.

Magni 2 builds on the performance of Magni, with even more refined sound and versatility, while Magni 2 Uber is now a complete desktop control center with preamp capability and even more power. Ready For Any Headphone The Magni 2 is ready for any headphone, from IEMs to hard-to-drive orthodynamics. Switchable gain provides the fine control and low noise floor you need for sensitive headphones, as well as the power you need for hard-to-drive high-impedance headphones and orthos. Even Better Sound and Performance Magni 2 is a newly refined, fully discrete, constant-feedback gain stage. It may sound like engineering but it’s important. Not only is the Magni 2 the only fully-discrete amps in their price class, they also use a new gain stage with constant feedback across the entire audio band. No op-amp can claim to do this. In addition, Magni 2 Uber’s gain stage is even more sophisticated, for higher performance. Both are fully DC coupled, with no capacitors in the signal path. A Complete Desktop Control Center: Magni 2 Uber If you need preamp outputs for powered desktop monitors (or for connecting to any power amplifier), or if you want even more power and performance, step up to Magni 2 Uber. With a more sophisticated gain stage and 3x larger power supply, it delivers power and performance far beyond anything at its price. Made in USA By “made in Usa;” we mean made in Usa. The vast majority of the total production cost of Magni 2 —chassis; boards, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office, and our chassis guys are just over the hill in the Valley. Yep, the wall warts are from China, but there you go. There is some give and take to reach this price point. 2-Year Warranty Magni 2 is covered by a limited warranty that covers parts and labor for two years. That’s 2x the coverage of most amps in this price range.

No matter what uDAC you choose to start with, you can expect to hear detail, warmth and clarity from your computer's digital audio files you've never heard before. On listening at low volumes: If you're using the uDAC-2 with sensitive in-ear earphones and listening at low volume, please read this article about channel imbalance issues . Notes For Recording Engineer: The uDAC-2 is designed for consumer playback of digital music and has not been calibrated for professional recording. At the 9 o'clock volume indicator, there is hardly any signal; further, analog pots do not behave reliably. At normal listening levels, the volume tracking is within 1dB. The uDAC-2 volume maxes out at around 0dB input (maximum digital input). Thd+N around 1% is intentional to target the voltage rail limit in order to achieve the loudest possible, but distortionless, music playback. Short of 1% THD at 0dB input, the Dac2 is not at its voltage limit, which results in diminished volume for music.

Teac Ud-501 Desktop Headphone Amplifier & USB Pcm/dsd DAC - Black
HK$ 5,436.00
TEAC's new Ud-501 is the star of the 501 series. The Ud-501 supports Direct Stream Digital (Dsd) playback at either 2.8 MHz or 5.6MHz (Dxd) rates. PCM audio is supported up to 384kHz/32-bit resolution. It connects to your computer over USB using Asio 2.1 or DoP. The output section of the Ud-501 features two BurrBrown 32-bit DACs per channel and JRC Muses op amps, also with a dual monaural design. Both balanced XLR and unbalanced RCA outputs are available to connect to your power amplifier. A toroidal-core power supply ensures top performance and clean transient playback, for quality that outperforms components five times its price. Advanced Digital Circuits for Hi-resolution Audio Formats DSD 2.8/5.6MHz Native File Playback by Asio 2.1 or DoP Both 2.8MHz and 5.6MHz DSD files are processed in native mode to properly convert DSD into an analog signal, and skipping PCM conversion in between. Asio2.1 and DoP (Dsd over Pcm) playback are also supported. (Mac supports DoP only, with standard driver) Up to 32bit/384kHz PCM File Playback With PCM file format, files from 44.1kHz/16-bit to 384kHz/32bit resolution are supported. Asynchronous Transfer Mode Transfer timing is controlled by more accurately by ignoring the clock signal from a PC, nearly eliminating clock-noise and allowing digital data to travel un-affected. Variety of Digital Filter Settings and Preferences Three types of digital filters are provided for PCM playback, while 4 types of cut-off filters are provided for DSD playback. Also, shutting down unnecessary circuits – USB circuit when S/pdif inout is selected, or Line Out circuit when Headphones are connected – for purer audio processing. Reducing Jitter Noise by 192kHz Up-Converting With a PCM file sampling at a frequency less than 192kHz, users are able to convert up to 192kHz in order to reduce jitter noise, or keep the original sampling rate to enjoy the original sound. Pure Audio Circuits With Classic Audio Pedigree Dual Monaural Circuits to Eliminate Signal Interference and Maximize Performance. Every single part of the digital and analog sections are designed in dual monaural design to eliminate interfering noise to other channels. This maximizes the potential of the the DAC and the operational amplifiers, and achieves a purer audio processing signal. 32bit-compatible BurrBrown Pcm1795 on Each Channel The celebrated BurrBrown Pcm1795 D/A converter is used on each channel, which supports 32bit audio with a 123dB S/N Ratio. D ual Muses8920 Operational Amplifier on Each Channel Two Muses8920 operational amplifiers are used on each channel. The Muses8920 was developed for hi-fi components to deliver clear, 3-dimensional sound.

Using a pair of power transformers, one each for the left and right channel, ensures that current is delivered exclusively to each channel. RCA Output with Parallel Buffer for Better Drivability Two operational amplifiers are connected in parallel with the line out circuit section to improve of line-out signal drive. This helps achieve a more linear analog output signal than any other known method. Large Number of Inputs & Outputs for Full-Scale Hi-Fi System Integration The Ud-501 provides two optical and coaxial digital inputs, one pair of XLR and one pair of RCA analog audio outputs. The RCA lineout jacks have an exclusive clearance zone, so a high grade pin cable with a large shell is able to be connected. The output terminal is selectable to either RCA or Xlr. The XLR output connectors have switchable polarity, either pin 2 HOT or pin 3 Hot, to accomodate vintage amplifiers. A standard detachable IEC cable with 3-polar socket allows user to upgrade to high-grade AC cables.

 Meridian Prime Desktop Headphone Amplifier at 11965.00 HKD from TREOO.com
Meridian Prime Desktop Headphone Amplifier
HK$ 11,965.00
Overview Recently, the headphone market has greatly increased in popularity, and for many it is the primary way to experience music. This choice is based not only on performance, but also feel, comfort, and style. It is with this in mind we introduce Meridian Prime Headphone Amplifier. With a new chassis design instantly identifiable as Meridian Dna, Meridian Prime delivers lifelike performance from any headphone and is designed to appeal to audio enthusiasts who seek the highest possible performance from conventional analogue audio sources. Meridian Prime provides three inputs, one dedicated and optimised to USB sources for computer audio, discrete pure analogue inputs on RCA for traditional sources, and a 3.5mm connection for portable devices such as a smart phone or tablet. Asp, or Analogue Spatial Processing, is an option for “outside the head” listening through headphones. Design Despite its diminutive size, Meridian Prime echoes the design elements of any other Meridian product, including a double skinned, bead blasted metal chassis found on Meridian’s full size components. This ensures that noise is kept away from critical audio components for lifelike details that are critical for headphone listening. The Meridian Prime Headphone Amplifier can be powered by the wall- mounted supply provided, or by the similarly sized, and styled, Meridian Prime Power Supply for even higher audio quality. The use of an external power supply means that AC noise is kept well away from the pure analogue stages of the Headphone Amplifier. Virtually all the active audio components are at the rear of the unit, as close to the connectors as possible to minimise the audio path length, and are essentially remote-controlled from the front panel. This is even true of the volume potentiometer, a high-quality Alps-type mounted near the rear of the unit, which controls the level of all outputs. A special flexible shaft coupling is employed to avoid microphony, resulting from operation of the volume knob. An analogue output is also provided so the product can be connected to an active loudspeaker, or conventional amplifier and loudspeaker system for a high-performance simple system. A 6-layer circuit board provides ground-planes and maximises signal isolation. The product is DC-coupled, for outstanding low frequency control and overall audio reproduction, and absolute phase is maintained throughout. Technology Meridian Prime will appeal to even to most demanding users with its range of input connectivity, performance, unique features, and build quality. Three front-panel headphone sockets are provided, optimised for purpose. One is a 3.5mm stereo socket for the connection of earbuds and similar devices, which presents an output impedance of 2Ω to suit these devices. The other two sockets offer an exceptionally low impedance (around 3mΩ) and are standard 1/4in stereo (tip-ring-sleeve) types, carrying both channels. They can be used to connect two pairs of headphones, or to attach a single pair of headphones wired with separate cords for left and right drivers, thus offering the opportunity to reduce headphone crosstalk. In addition to simply replaying stereo audio at the highest possible quality via headphones, the outputs also include two “Analogue Spatial Processing” modes, i and ii, which replace the typical “in the head” experience of headphone listening with a smooth, natural feeling of spatiality that is much more like listening on a pair of loudspeakers in front of the listener. The USB conversion system is powered from the interface, meaning that when it is disconnected, all digital circuitry in the unit is deactivated. The fully asynchronous USB 2.0 interface supports signals at up to 192kHz/24-bit sampling and includes Meridian resolution enhancement techniques such as oversampling and Meridian’s unique Apodising filter. Prime Apodising Filter Filters are critical in digital audio. Commonly they introduce distortion and harshness because of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.

After a full year research and development, our engineers have designed a unique personal amplifier with excellent sound quality supported by a long lasting battery. Just like our any other products, Rendition 1 carries the Heir Audio signature of exquisite design concept with the delicate black carbon fiber on the both sides. Rendition 1 has further expanded our product line and once again reinforced our belief that each one of our products is a unique acoustical and artistic expression of the beauty of music! The successful preorders have approved the acceptance of this wonderful amplifier! The Rendition 1 is an exciting portable amp, that in keeping with Heir Audio tradition, sounds as good as it looks, and looks as good as it sounds. The sound quality can be described as “black” (quite) or without back ground hiss. The concept behind the amp was to add more “depth” and “control” to the music, rather than adding colouration. If bass is present in the music, the amp is there, waiting to add more depth; if there are highs in the music, the amp delivers those as well cleanly and clearly. The Rendition 1 is available in two case colours, black or silver, accented with black carbon fiber, rendering a look of unsurpassed class.

Go ahead. Do things with Valhalla 2 that you’d never attempt with other OTL tube amps. Run low-impedance headphones. Use IEMs. Valhalla 2 is a complete re-imagining of Valhalla, with improved performance, higher output capability, lower distortion and output impedance. Tubes Made Flexible While most tube OTL amps are really only designed for 300 ohm Senns and 600 ohm Beyers, Valhalla 2 stretches to include headphones that you’d never expect to use with a tube amp. Go ahead. Use it with Grados. Run it with AKGs. Rely on it for many IEMs. You may even like it with high-efficiency planars like Lcd-X, Lcd-Xc, Oppo Pm-1 and He-400. A Complete Desktop Preamp Valhalla 2 also adds two important features: preamp outs and a gain switch. Preamp outs let you connect your powered monitors directly to Valhalla 2, to give them some of what some people call “tube magic.” The gain switch gives you better control of both output level and impedance, for better matching to your headphones. It's easy to build a complete desktop system around the Valhalla. Not Your Father’s Tube Amp If you’re expecting syrupy, tubby, euphonically colored tube sound, you’re in for a shock. Valhalla 2 is exceptionally accurate, neutral, and resolving, without being strident or etched. Made in USA By “made in Usa;” we mean made in Usa. The vast majority of the total production cost of Asgard 2—chassis; boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley. 5-Year Warranty Asgard 2 is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. Five. Which is up to 5X that of our competition, if you weren’t so hot at math. Note the marketing weasel-wording “up to.”

Grado RA1 Reference Desktop Headphone Amplifier (Battery)
HK$ 3,260.00
After years of relying on other equipment to drive Grado headphones, you can now listen and enjoy headphones through our new Grado Reference Headphone Amp, the Ra1. Designed for state-of-the-art performance and specifically to play Grados, the new RA1 will allow you to hear your headphones like never before. This new amp is machined from a solid block of mahogany and measures 5" wide, 5 1/2" deep and 1 1/2" tall and weighs in at 12 oz. The RA1 is available in an AC version or can be powered by two 9-Volt batteries that will drive the amp for 40 to 50 hours of listening pleasure. And the sound? Just like all Grados: warm, smooth, full-bodied, non-fatiguing and rich. Hook it up to any line source (portable or in-home) and drive your Grado headphones to their full potential. The Grado Labs RA1 headphone amp was designed specifically to drive Grado headphones and it does that quite decently indeed. It's recommended for use with fairly efficient (low impedance) headphones like the 32-Ohm Grado Labs headphone line. This is the battery-powered amp unit. The 'AC-power' Grado RA1 (Ac) version is also available. The RA1 design is small and fairly light for portable use, although that trad Grado wood-block design makes it somewhat bulky for easy travel and mobile listening on the fly. It's a very simple yet effective & the front panel sports a volume control, an on/off LED light, and a full-size 1/4" headphone jack. The rear of the amp provides an on/off switch and one pair of left/right RCA inputs. The battery compartment holds two 9V batteries, and is easily accessible via a metal plate with two screws located on the bottom of the amp. One bummer: the battery-powered Ra-1 does not operate with a wall wart/AC adapter.

Audio sounds richer and fuller, with more clarity on the high and and more depth and power in the mids and lows. You'll hear details in your favorite music you never heard before. Your favorite headphones and speakers reproduce sound to their full potential. About Asynchronous USB Audio The uDAC-2SE (Special Edition) and uDAC-2SGE (Signature Gold Edition) are designed for Asynchronous USB Audio mode. The difference between synchronous and asynchronous USB audio is detectable by most, but best left for the individual audio enthusiast and audiophile to decide. That's why if you're new to appreciating high-quality USB audio, we recommend that you start with our baseline uDAC-2 model without Asynchronous USB Audio to avoid the more involved setup required for AA. If you ever decide to upgrade to a uDAC-2SE, we provide the option to purchase a kit (Sgd $189) that includes a replacement circuit board and stainless steel front and back panels* *For more information, please refer to the Async USB Audio FAQ and Setup Guide. No matter what uDAC you choose to start with, you can expect to hear detail, warmth and clarity from your computer's digital audio files you've never heard before. On listening at low volumes: If you're using the uDAC-2 with sensitive in-ear earphones and listening at low volume, please read this article about channel imbalance issues . Notes For Recording Engineer: The uDAC-2 is designed for consumer playback of digital music and has not been calibrated for professional recording. At the 9 o'clock volume indicator, there is hardly any signal; further, analog pots do not behave reliably. At normal listening levels, the volume tracking is within 1dB. The uDAC-2 volume maxes out at around 0dB input (maximum digital input). Thd+N around 1% is intentional to target the voltage rail limit in order to achieve the loudest possible, but distortionless, music playback. Short of 1% THD at 0dB input, the Dac2 is not at its voltage limit, which results in diminished volume for music.

 Schiit Audio Magni Desktop Headphone Amplifier at 1029.00 HKD from TREOO.com
Schiit Audio Magni Desktop Headphone Amplifier
HK$ 1,029.00
Magni is the only fully discrete headphone amp under S$200 that is made in the Usa. Delivering 1.2W of power into 32 ohms, Magni is ready for virtually any headphone—including many hard-to-drive orthodynamic models. Discrete Design, DC Coupled If you ain’t into engineering, you can probably skip this section. But it’s important. All other amps in this price range use op-amps for gain. Not Magni. It uses a discrete gain stage design, with low-noise Jfet inputs, fast VAS transistors, and massive output power transistors. The result is greater current capability for higher power output. We’ve also used a DC servo to eliminate coupling caps from the signal path. From IEMs to Orthos Magni is quiet enough for many IEMs, but provides up to 1.2W into 32 ohms, which is plenty for many orthodynamic headphones. Magni is versatile enough to be a “do all” amplifier—it may be the only amp you ever need. Made in USA By “made in Usa;” we mean made in Usa. The vast majority of the total production cost of Magni—chassis; boards, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley. Yep, the wall wart is from China, but there you go. There is some give and take to reach this price point. 2-Year Warranty Magni is covered by a limited warranty that covers parts and labor for two years. That’s 2x the coverage of most amps in this price range.

 JDS Labs Objective2 Desktop Headphone Amplifier - Black at 1138.00 HKD from TREOO.com
JDS Labs Objective2 Desktop Headphone Amplifier - Black
HK$ 1,138.00
The Objective2 (O2) is an open source headphone amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost. This item includes a fully assembled and hand tested O2 amplifier, ready for use. You will only need an AC adapter suitable for your region. The O2 has created a stir in Head-Fi.org’s do-it-yourself community. After being banned from Head-Fi for heated discussion, he proceeded to design O2 for maximum benchmark performance to prove his points. It’s large and heavy, so hardly worth consideration as a portable amp, however, O2 lives up to its name. For more information on the O2, please refer to NwAvGuy's O2 Details article. Note: You need a separate power adapter with this device. If you do not have one, please add the G.e.z. 15Vac Power Adapter to cart. Customisation The default gain levels of the Objective2 are intended to work well with over 95% of headphones on the market. We use the stock O2 with headphones as low as 16 ohms @ 108 dB/mW, and as high as 600 ohms (very high and very low efficiency, respectively). There is no reason to change the stock gain unless you regularly listen at extremely low volumes. Gain can easily be changed by removing two resistors. You may choose for JDS Labs to set gain of 1.0x/6.5x or 2.5x/1.0x, and such customisations will only be on pre-order basis (2-3 weeks).

 Questyle Audio CMA800i Desktop Headphone Amplifier & USB DAC at 20676.00 HKD from TREOO.com
Questyle Audio CMA800i Desktop Headphone Amplifier & USB DAC
HK$ 20,676.00
Excellent Headphone Amp Section The Questyle Audio CMA800i headphone amplifier section follows Questyle’s patented "Current Mode Amplification" design used in their flagship headphone amplifier, the Questyle Audio Cma800R, in fact , most of the components used are the same. The ultra low 0.00026% distortion, ultra wide bandwidth, up to 850kHz (+0, -3dB), and Super-current pure Class A architecture enables the Questyle Audio CMA800i’s amplification to be unparalleled among all-in-one DAC/amplifier models. A World Class DAC section Unlike other DACs that claim DSD support, yet in actuality provide DoP (Dsd over Pcm), the Questyle Audio CMA800i accepts the DSD bit-stream directly from your computer, bypassing your computer’s audio processing and digital volume control as well as the Questyle Audio CMA800i’s digital filters, to provide True Dsd, the way it was meant to be heard, without requiring expensive difficult to install proprietary connectors, or as is the case with DoP breaking up the bit-stream into 16bit packets and compressing them into a PCM data-stream and then uncompressing them at the other end, buffering them, then reassembling the bit-stream so that it may be sent to the DAC as Dsd, all of which requires an extreme amount of processing at both the computer end and the DAC end to perform in real time (which invariably leads to latency, data loss, etc), not to mention a 33% increase in bandwidth requirements for the USB ports and cabling. IIR Digital Filter Currently the majority of DACs use FIR (finite impulse response) digital filters, but research and testing has shown that our ears are very sensitive to the pre-ring that FIR digital filters add to the impulse wave, making the music sound incoherent and unnatural. The Questyle Audio CMA800i offers the more advanced IIR digital filter, which completely eliminates the pre-ring from the impulse wave producing a more natural sound. Seperate Pre-Amplifier Section The Pre-Amplifier output is another unique feature of the Questyle Audio CMA800i. Many manufacturers, when designing an all-in-one model, use the headphone amplifier circuit loop to support the pre-amplifier output to reduce costs. To achieve the best possible sound performance, the Questyle Audio CMA800i is designed with a totally independent pre-amplifier, even the power supply supporting the pre-amplifier circuit is independently located. In keeping with Questyle Audio’s no-compromise approach. and to make usage more convenient, an analog volume control circuit is employed, using an Alps27 motor controlled potentiometer for operation via remote control. Hi-End Components Throughout Superior sound performance requires the use of Hi-end components. Questyle uses only the very best in the Questyle Audio CMA800i, each component undergoing an extensive testing and selection process, with many being custom made and purpose built. 10mm Thick Aluminum Cover and Bottom Chassis The Questyle Audio CMA800i aluminum chassis is produced by Foxconn using precise CNC tooling machines. The upper cover and bottom chassis “mutual bit” structure design, provides the Questyle Audio CMA800i with stable heat, excellent control of sympathetic vibration and excellent shielding from Rfi/emi radiation. Quality Control Each product is burned in for 72 hours before shipping and every product has its own serial number and test report. The engineers prepare two copies of the test report, one report is put in the box for the customer and another report is kept in a safety deposit box at Questyle. If there are any questions, about any product, at anytime, Questyle is able to find the report, for that unit, to aid in solving any issues. For distributors, Questyle can provide a professional technical guide.

Background: The release of FiiO E12 (flagship of portable amplifier) was welcomed by the market. However, for some customers who are eagerly to try on something new, the original operational amplifier--OP AMP (Opa1611+Lme49600) still can’t make them satisfied. At present, FiiO Company is not in the right place to offer customized service, and different combination of the OP AMP can hardly help the customers to find the most favorite one through the objective sound feelings. Yet, in order to show our appreciation to those old customers and bring more fun in enjoying music, we specially invest effort in developing the DIY version based on E12. We are expecting to offer more options to our customers with this higher playability platform. Quantity: 2000pcs at its most worldwide. (The program would be terminated if the reservations run less than 500.) Target customers: The following requirements are not non-negotiable, but it is Strongly suggested for those who are ready to reserve to read each item carefully in order to avoid any unpleasant purchase experience. 1. Have certain operational ability; Since the customers are required to replace the OP AMP with the help of our manual, we don’t suggest average user to purchase in order to avoid burnout caused by faulty operation. 2. Old users of FiiO who know well of its products and service; Owing to the high cost of the high quality audio OP (the supplier has no stocks available), we can only move to production process after got the Full Payment of reservation. The production cycle would be pretty long, and for now we are unable to promise a definite delivery date. That’s why we don’t suggest users to buy this item when they had never bought any FiiO products before, since we are afraid they would cancel the reservation due to impatience or lack of trust. 3. Willing to accept the terms without after-sales service; For the DIY version, since it is practical to open the case to replace the OP by the end-user, we can hardly tell whether the issue is out of quality or man-made problem. In order to avoid unpredictable loss, we would seal the fixed screws before sending out, once found opened, we would not provide related after-sales service. Features of the E12 Diy: 1. On one hand, reserves the fine and meticulous workmanship of its commercial edition; on the other hand, offers more different timbre and fun with different OP combination. 2. Canceled the Bass and Crossfeed function, which offers larger space regarding the inner wiring layout, thus get its performance greatly improved. 3. Reserves the excellent high voltage power supply circuit of E12, ensure to make the most of its high quality audio OP. 4. Reserves all kinds of protection circuits and USB smart fast charging of E12. As to normal DIY amplifier, audiophiles would not pay much attention to this kind of design, and lack conditions to use the MCU to fulfill this function. 5. All the components are purchased from the first-class agent in China of companies like TI, Adi, which definitely prevent getting fake products in the purchase of DIY

Amp up your Audio

Most mainstream headphones that are targeted towards the mainstream consumers come with many different sound qualities, and they often don’t require a lot of power to drive them. Just plug them into your computers or smartphones and you’ll be able to listen just fine. If you want to have some high-fidelity audio in your headphones however, they’re a whole different ballgame altogether.

High-end headphones are expensive, but they sound exceptionally good. While they delivery fantastic sound quality, expensive headphones tend to require a little bit more in terms of power; the typical computer and audio jacks on smartphones are usually not enough to power these headphones. That is where these headphone amplifiers come into play, giving these high-end headphones that much-required power boost.

The many different headphone amplifiers

Headphone amplifiers come in a variety of different shapes and sizes – as well as specifications and pricing. However, whenever people mention headphone amplifiers, it is commonly referring to portable amplifiers that can be taken around to be paired with digital audio players and smartphones. There are also desktop amplifiers that are made to power headphones at home, those are significantly larger and tend to require constant power supply rather than operate on a battery like most portable amplifiers do.

How to know if your headphones need an amplifier

There are several different ways to know if your headphones could do with the help of a headphone amplifier, and these are sometimes also conditional; some headphones may seem like they need an amp, but they don’t.

  • Your headphones sound quiet when plugged into your device, even at higher volumes.
  • Your headphones have a high impedance of 32 ohms or more.

Those two are the most common signs that your headphones could probably do with an amplifier. The issue with quiet headphones is more prevalent when it comes to mobile devices such as your music player or smartphone. The specifications of your headphone are also commonly listed on the back of the packaging where you will be able to see if it has a high impedance.

One thing to keep in mind that most in-ear headphones or earphones typically do not require the use of a headphone amplifier because they do not require much power. Most earphones are also optimized for use with mobile devices.
