Alright so I tried out the PreSonus Firebox as my output device and it seems to work well. There is a bit of a hissing noise, but it isn't that loud. I'm not sure if it makes me HD 201s sound better than through my X-Fi Go! Pro, but it sounds at least as good. I think the Firebox sounds a tiny bit cleaner/more airy.
I've read that the amp on this thing is super powerful and that it works fine with high end headphones, so I guess this will be my amp for when I do get better head phones!
