I don't write review often... But I made an exception for this little box.
First, it work WITHOUT power supply, and WITHOUT driver, no matter it is Linux or Windows (win10 at least).
Second, the sound quality is nearly indistinguishable (with my HD800S) using this FOSTEX vs Audio-gd 28.38 (whcih is 6!!! times more expensive). On the latter one sound is more opened, though (due to sabre ES9038 chip, i presume, but HD800S do not allow the sound to be bright at the same time..).
So, the high frequencies with AK chip is less vivid (actually that was the reason I have tried AK-based DAC).
If you have some "piercing" recordings -- this Fostex, or an AK- chip in general, is the way to go.
The only drawback of this DAC is: the sound level should be at about 7-8 mark to match sound mark 15-17 on Audio-gd (with Fast filter) with HD800S.
So, the 300+ Ohm headphones is not the way to go. The sennheiser PX100, 200, 300, as well as Sennheiser (new) HD660 is the way to go, most likely. I have tried my OPPO PM-2 (nominal imp. = 32 Ohm) with Fostex, and still the sound knob should be on the mark 6-7, which may produce saturation. (NO WAY to use sound level in your PC sound control >100% - clipping is, of course, SOOOO evident!).
The conclusion: It's a marvel for headphones with < 300 Ohm impedance. Sound is approaching the high-end standards (it will be indistinguishable in the office conditions, used with NOT-a-high-end-but-still-amazing Sony WH-1000X), begin colored differently though.
