Exceptional device

Spirit_Agent, 22.04.2018
Ridiculously high quality unit with a very polished, non-fatiguing sound, has just about any feature you can think of and the new FS revision even further reduced any jitter. I personally did comparisons between the ADI-2 Pro, Chord Hugo 2, and the Mytek Brooklyn DAC+ and the ADI-2 Pro won in terms of both sound and features.

Pro's:

- Very clean and detailed sound without being harsh
- Almost non-existent jitter (far below audible ranges)
- Excellent DAC
- Excellent headamp
- Excellent pre-amp
- Excellent ADC
- Best USB implementation I've seen to date (even beats USB conditioners/decrapifiers)
- Ability to monitor, excellent for mixing
- Absolutely filled with useful features
- Compact
- True balanced headphone output (adapter not included)
- Drive 2 headphones at once (very handy for comparing)
- Plenty of power on tap, both balanced and unbalanced.
- Very easy to switch from headphones to monitors
- SOTA specifications, along the lines of a Benchmark DAC 3

Cons:

- Slightly pricey but still better and cheaper than direct competitors by a fair margin.
- Not the last word in detail retrieval, soundstage, organic-ness etc but very close nonetheless, a clear audible upgrade would cost at least over 4000 euro

This little box is RME's masterpiece, and I don't see anything coming close to it's sound and features anytime soon in the same price range for both Hi-Fi and professional usage.

Probably the best conversion and HP amp I've ever heard

Shane67, 08.01.2018
This unit is stunning in appearance, build and features. I use it as an audio interface, playback DAC and mastering AD/DA converter. Weighing at 1kg I can bring it almost anywhere and plug in my AKG K812 headphones that match incredibly well. The headphone amps alone are with the price point, and all the extra features and practicality make it my most versatile and overall favourite single piece of gear. Amazing!!!
