iFi Micro IDSD Signature Portable DAC / Headphone Amplifier. Its a powerful amp in small packaging with battery. I used it on my headphone one as it needs quit a bit of power most DACs cant provide for best sound. Coated 800 pounds and goes about 750 new now . Barely used I can count how many times I charged it which is about five times. Upgrading so this is going as part of my spring cleaning .. Excellent condition almost new. And battery is in great condition because used so little bought about a year a go . Its proper dam/amp for high quality sound No returns can pick up if you live in London Review https://headfonics.com/ifi-audio-micro-idsd-signature-review/ Will only send with the royal mail insured. Tracked postage . No returns so make sure thats the dac you want.

This a very highly-regarded headphone amplifier. It sounds amazing for its size and price. It is very powerful, fully able to drive planar-magetic headphones - it pairs exceptionally well with MrSpeakers Aeon Flow Closed for office use, for example. But it sounds great with everything Ive tried it with (Focal Clear OG, HifiMan Sundara, Sennheiser HD600 and HD650). Check out the many many reviews here: https://www.head-fi.org/showcase/ifi-audio-micro-idsd.20201/reviews The amp has a ton of features and configuration switches, which I tend not to use - I set it to what is most neutral and forget it. This model has been discontinued, replaces by the Micro iDSD Signature, which sounds too bright and harsh to some; hence this original model is still sought after. It is what some of the well-known headphone reviewers out there use for their headphone reviews, for example https://crinacle.com/rankings/headphones/ Comes in its original box with its original accessories. Non-smoking pet-free household. Product page: https://ifi-audio.com/products/micro-idsd-bl/ Free shipping to Germany! Outside of the EU? Shipping outside of the EU can be expensive.

iFi Micro iDSD Signature Transportable DAC and Headphone Amp Excellent condition, original owner, sounds incredible. All pictured parts included, RCA cables, USB data plug, USB charging plug, USB converter, silicone mat, optical converter, RCA caps, original boxes (just missing manual, bag, and rubber bands), 1/4 converter upgraded to one easier to pull. Took great care not to let the battery die, always keeping in the ideal range of 30-80% charge for longevity. Hardly traveled with the unit and ultimately use my desktop setup more, so decided to sell. Overall the sound signature is incisive, energetic, wonderfully detailed, fantastic punch and slam characteristics - a great partner to the Focal Clear and Arya Stealth. The bass boost toggle is especially handy and well implemented, many other bass boost implementations bleed too far into the mid-bass which makes it muddy. The DAC RCA-out is very good as well, comparing it against half a dozen (less expensive) DACs it is the clear winner. It runs simultaneously with the AMP section so switching outputs is not required. Both AMP plugs (4.4 and 1/4) work simultaneously so if you have headphones that work for both you can listen with someone else. Overall this is a fantastic DAC / Amplifier, at this, or any price point.

Excellent condition. It comes complete with all original accessories and packaging, plus a USB-A(f) to USB-C(m) adapter so you can plug it straight into a phone.

This is an excellent sounding DAC. The exterior is in very good condition. As you may observe in one of the pictures, some pixels on the display are not displaying as brightly as others. Otherwise, I would probably describe this as near-mint condition. Pre Box S2 Digital Digital micro preamplifier with MQA and DSD512 support. A performance revolution in a small package! Pre Box S2 Digital marks a new era for our S-series components. For the very first time we are using a dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures highest class audio in a small and affordable package. This DAC is capable of high resolution audio up to 32bit/768kHz PCM and DSD512! Pre Box S2 Digital is also the very first of our devices to support hardware MQA unfolding. It’s also the premiere of our proprietary Optimum transient digital filter and our proprietary clock circuitry design. Digital audio is the art of time, with our new proprietary clock design we have managed jitter rates of unrivalled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators! MQA hardware decoding is only possible via the asynchronous USB input of Pre Box S2 Digital. With organic polymer capacitors and thin film miniMELF resistors we were able to create a tiny device that will blow away even much bigger components for a much higher price. With a total of eight digital filters the sound can be shaped precisely to the listeners liking. Pre Box S2 Digital is fully remoteable, it can also control the playback software of a computer. You can use Play, Pause, Forward and Rewind straight with your Pre Box S2 Digital!
