I have been using this unit for around 6 months with K7xx and Hd6xx. While the amp section is great, the dac itself is a terrible performer. It has no attack and has poor dynamics and details. When I feed it dsd signal (through Audirvana) the dac performs even worse. Now I have a Aune X1s (occassionally Fiio X5ii) feeding signal to this unit and this combo is pretty good. However if I wanted just a pure class A amp, I could have gone with Nuforce HA-200 (in fact I've ordered it too).

trybeingarunI finally did the mods specified in the head-fi page pasted below. The difference is quite mind blowing. If you've bought this unit, do yourself a favor and do this mod. The best part is it's pretty cheap $30 for capacitors + recapping fee. The dac performs much better now. Mainly the highs aren't shouty and compressed and the sound stage doesn't feel like a dumbbell and more oval. Now when I compare Aune -> Matrix vs Matrix alone the aune has a noticeably grey background.
