With iEMatch there to dial to suit any IEM, the micro iDSD has redefined the headphone amplifier class. Used along with the analogue volume control, the diminutive size of the micro iDSD belies its uncanny ability to drive virtually anything and everything! SmartPower® is the micro iDSD’s onboard recharging feature for Smartdevices. Its 4800mAH battery is able to fully recharge an iPhone two-times. Compatible with Apple and Android, phones and tablets, it is another example of iFi’s commitment to customer needs – enjoy high-end audio on the go without worrying about the phone going flat. iFi’s iCAN and iTube have already achieved widespread acclaim, so much so that their core features including 3D Holographic and XBass have become renowned in their own right and imitated by others. In the micro iDSD, for the first time in an iFi product, it features XBass and 3D Holographic for Headphones and Speakers. All these features are still executed in the analogue, not digital domain to preserve the original music format. And so much more….with the amazing Crowd-Design program, we are over the moon that you, the customer was central to the development of the micro iDSD. The micro iDSD is literally bursting with features – such as Direct/Pre-Amp, 3.5mm input, SPDIF Input/Output and much, much more.

For sale Oppo HA-1 DAC & headphone amplifier. The amplifier has been very well taken care of (still has the original screen protection film) and is in very good condition (minor imperfection in the upper right corner next to potentiometer - hardly visible, check pics). Exquisite build and fantastic quality. Included:  - Oppo HA-1 DAC & headphone amplifier  - Remote control  - Power cord (EU)  - USB cable  - SPDIF coaxial cable The item will be carefully packed and sent via tracked and insured shipping. HIGH PERFORMANCE AUDIO - Discrete Class A Amplifier A Class A amplifier conducts signal over the entire range of the input signal cycle. The output transistors are biased to operate in their most linear range, and there is no crossover distortion caused by switching the signal between two push-pull devices. The HA-1's power amplification circuit for the headphones is Class A built with discrete transistors. The discrete design allows us to hand-pick and match the best parts to build the HA-1. - Toroidal Power Supply A toroidal power transformer offers superior power efficiency and much lower exterior magnetic fields over traditional laminated steel core transformers. The HA-1's toroidal linear power supply provides a very clean and robust power source to the audio components. - Fully Balanced Design The internal analog audio signal path of the HA-1 is fully balanced. For digital audio, the signal runs in balanced mode all the way from the DAC to the output jacks. Balanced analog input is kept intact, and single-ended input is converted to balanced at the input buffer. All single-ended outputs are derived from the balanced signal as well. The balanced design provides better common-mode noise rejection and improves signal quality. The balanced headphone output provides twice the voltage and four times the power of the single-ended output, enabling the HA-1 to drive the most power hungry headphones. It also provides better channel seperation by eliminating the common ground return path. - ESS Sabre32 Reference DAC The DAC is one of the most important components for digital audio playback. The SABRE32 Reference ES9018 from ESS Technology is the world’s best performing 32-bit audio DAC solution targeted for high-end consumer applications and professional studio equipment. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented DNR (Dynamic Range) of up to 135dB and THD+N (Total Harmonic Distortion plus Noise) of -120dB, the industry’s highest performance level that will satisfy even the most demanding audio enthusiast. To learn more about the technologies behind the exceptional performance of the SABRE DAC, please read the SABRE Technical White Paper. OPPO HA-1 4.3" information display - Clean Signal Path The HA-1 uses an analog potentiometer (the familar volume knob) to control the volume. By avoiding re-digitizing the audio signal for volume adjustment, the HA-1 provides a clean signal path for the audio. At the same time, the convenience of modern digital volume control is not lost - a remote-controlled motor turns the volume knob and a 10-bit analog-to-digital converter samples the signal to display a numeric dB level. - Made for iPod®, iPhone® and iPad® The HA-1 passes Apple's "MFi" certification and is compatibile 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. - Wireless Audio via Bluetooth The HA-1 supports Bluetooth Advanced Audio Distribution Profile (A2DP) with both the standard and aptX® high quality codec. Simply pair your phone with the HA-1 and set music free

In perfect working condition and aesthetic, comes with remote control, power cable and manual. No box but will be extremely well packaged. Beautiful equipment, very flexible and elegant, exceptional sound. The only 'downside' is the discoloration of the volume knob (a well-known problem if you do a research), but that obviously does not impact the operation and didn't bother me at all! r e m u s i c. i t /EN/Bel-Canto-DAC25-processor-80784100 b'"'In conclusion, I can say that the Bel Canto 2.5 is a DAC of absolute modernity. For the quality of its sound, the superb engineering and the ability to handle analog sources, it represents an incomparable article in terms of versatility.b'"' a u d i o p h i l i a. c o m / reviews/2016/5/24/the-bel-canto-dac25-dac-controller b'"'I’ve experienced digital done right. The Esoteric and dCS gear I’ve heard are knockouts. And crazy expensive. Got the dosh? Go ahead. You can't beat them. But this bel canto DAC is less than 2K! It’s a lifetime DAC and worth twice the price. You won’t need anything else for a long time. And, you can sell your preamp to buy it! In the here and now, this exceptional US$1,999 DAC will be staying in my system for a while. And, I’ll enjoy every minute with it. Very highly recommended.b'"' The $2000 Bel Canto is an excellent PCM digital audio converter, and while it is not exactly cheap as a standalone DAC, given the features it offers, it would be difficult to give the DAC 2.5 less than a high five. The DAC 2.5 is an incredibly versatile music machine. Thanks to its stereo RCA analog input, the 2.5 can be used as an analog preamp. It features 24-bit digital volume control and a host of connection options. In addition to built-in USB, a host of 24-bit/192kHz compatible inputs (Toslink, AES/EBU, S/PDIF) share the rear panel with XLR and RCA analog outputs. There is also a front-mounted 1/4b'"' headphone jack for the dedicated headphone amp. It took me a while, but I finally put my finger on a key attribute of the Bel Canto: it digs deep into the music, reconstructing a sonic image that is sometimes very bright and always transparent. The smoothness of the sound is just enough to give you a tube feel, but the Bel Canto is completely solid-state. It is very easy to get lost in the music the Bel Canto is presenting to you. I have thrown a ton of music at the Bel Canto and it just presents it beautifully. The detail in the music is just insane. I mean, it is so detailed without being analytical at all with a nice slightly warm character... a nice rich midsection and great extension in the bass and treble. I think it was really musical, with a really high-end rhythm.

Little jewel, one of the greatest headphones amplifiers ever, extremely rare on sale, in perfect working condition and aesthetics, almost like new. Trully impressive, addicting sound. Higly regarded by audiophiles, a true reference and a collectible item. Would loved to keep this one, I'm selling it reluctantly... Comes with original box and accessories, well packaged. Would consider posting it internationally but please, ask for a quote as the postage differs from country to country and the amount in the description is for European Union only, thanks. b'"' In terms of the criteria that I listen for in any amp, transparency, noise, dynamics and the ability to get me out of my head and into the music, Prime is well, prime. All in all, a seemingly impressive effort that covers all the bases.b'"' From Neil Gader's review in The Absolute Sound head-fi.org/threads/meridian-prime-headphone-amplifier-review.691392/ Headfonia: MERIDIAN PRIME - ENGLISH EXCELLENCE b'"'Does The Prime Live Up To The Meridian Name? First I tried the Prime as an Amp/Dac combo (with PSU) and I immediately loved the sound from this demo unit: Enormous Clarity, great detail retrieval from bass to treble, top precision and dynamic sound. All presented with just the right amount of air between the instruments. Musical and detailed sound with a superb flow. The Prime sounds fast and is neutrally tuned but the best solid state kind there is. Maybe it is just slightly forward sounding, but not that much. Bass is tight, goes deep, is well layered and has a lot of detail but doesn’t have the big body of say the Beyerdynamic A20 amplifier (but it has far better quality). The Prime is a linear tuned unit and I find the bass to be perfect (and that’s an understatement) with the Audeze and Hifiman headphones but more on those later. The Prime’s mids are slightly more forward sounding, especially the vocals, but they are not bright. Don’t get me wrong on that because they sound incredibly good: perfect separation, great timbre, heaps of detail but never over-analytical and always musical and dynamic. Treble is extended and detailed but never harsh sounding. I do like my treble and the Prime does a splendid job for my taste. Treble is on the same level as the mids and bass: clarity, detail and sparkle. The Prime’s sound stage is wide and deep with a perfect balance and 3-dimensionality. I fell in love with the Prime’s sound as a DAC/Amp unit. For me this is top audiophile sound.b'"' The Prime can also be used as a DAC and Pre Amp in combination with a power amp, headphone amp or active speakers. There is no disappointment here, the Meridian DAC delivers a stunning performance in combination with my desktop sized solid state and tube amps. I love a clear, detailed and neutral DAC with a huge sound stage. Who wouldn’t? Well this is one of those DACs I could live happily ever after with. It ads nothing to the sound, in a good way that is, and using it as a pre amp boosts the performance of your amplifier. headfonia.com/meridian-prime-english-excellence/ The Prime is a top-class headphone amplifier and a surprisingly talented stereo preamp. Meridian is a master at signal processing, so it’s no surprise to find ‘Analogue Spatial Processing’ on board the Prime. It’s a function designed to counteract the fact that stereo recordings are designed to be played over speakers, not headphones. ASP blends the left and right channels to varying degrees – there are three options – to try to create a more natural presentation. These features can often compromise clarity and focus to improve sound staging, but ASP sounds pretty convincing. The Prime also works well as a dedicated stereo preamp. It’s certainly right up there with some of the best preamps we’ve heard at around the £1000 mark. En savoir plus

The sound is exceptionally clean with just the right amount of warmth, open space, no harshness from the 8 Sabre based DAC chips, the way it is implemented and also, most importantly, the proprietary patented b'"'Current Driveb'"' technology used by Apogee in the amplification stage. This goes a long way to explaining how this can drive 90% of headphones... with ease. Comparisons with all my previously owned DAC amps like Dragonfly Red, Cobalt, Topping DX 3 Pro, Fiio K5, K7, Ifi Zen Can V2, Cayin RU6, THX Onyx, Ifi Nano ISD Black Label add up to the Meridian Explorer outshining them all.

For sale iBasso DX90 DAP, with original box and accessories, in excellent condition (has always been used with protective screen and case), working perfectly. While pretty good in its original form, iBasso engineers did cut some corners and the player does not reach its full potential. As such, the player has been extensively modified in order to improve performance:  - power supply and DAC stages have been redesigned in order to reduce the overall distortions and noise level, in particular at lower frequency where the original suffers the most (around 5dB THD+N improvement at 1KHz, 30dB (!) improvement at 20Hz)  - output buffering stage has been modified in order to improve performance with lower impedance earphones (with 16ohm load THD+N is improved by approx. 30dB) Measurements with a professional audio analyzer show that the modified player is reaching excellent performance under real life test conditions (line out: -105dB THD+N across pretty much most of the audible frequency spectrum, headphone out: -102dB THD+N while delivering 500mVrms under a 16ohm load). Included:  - DAP  - Original battery (in very good condition) + new spare battery  - USB cable  - Coax SPDIF out cable  - Burn-in cable  - Silicone case  - Spare screen protector (one already applied) The item will be carefully packed and tracking number will be provided.
