Pros: Great build, nice sound, DAC + Amp combo, USB powered, different gain levels available
Cons: USB powered, requires drivers on Windows, reduces laptop battery life
Really quick, bought this at Canada Computers for a song, and it's been a great piece of kit! I had been agonizing on picking on a portable DAC/Amp combo for use with my laptop on the go, and this fit the bill perfectly. Blows the stock audio jack out of the water for sound quality, tightening up the low end, and opening up soundstage on the cans I've been using with it (SHP9500 and UE900), and construction quality looks like it's built to last.
