Pros: Hi-Fi grade sound, XLR and RCA Line out, several digital inputs including USB.
This will be short cause I don't have much time right now. I just got this on an impulse buy on clearance (open box). At $160 I could not resist.
Sounds amazing via USB on Windows 8.1 with latest drivers. I don't have alot of higher end DACs to compare it to but I have had alot of aftermarket sound cards and decent portable Amp/DACs like the TEAC HA-P50. It's a huge step up from that, which was my previous daily DAC/Amp. Very neutral, bass is very well controlled.
The headphone amp is a good pair with all my headphones from 20-300ohm. The HD 600 needs no more than 11 o'clock on the dial. I thought my HD 600 was already great, now it sounds simply divine. My only gripe is the lack of volume control for the Line Out. Overall I am very pleased indeed, specially at this price. But I could see how some would pay $500-600 and never look back. I would if I wasn't so poor.
