In reply to madmallard:
I don't actually like their stuff a whole lot, but they were the only affordable multi-input DAC i could find, and i find that DACs don't have much sonic impact on my system. By that i mean i can't hear the difference between the Emotiva, Cambridge DacMagic, Peachtree, etc. They all sound better than no dac, though.
I've had an XPA-2 amp. It was... Powerful and loud. Would use in an HT setting. Was pretty bright and shrill though. Too much so for my ears and music.
