Well my first post after lurking for a long long time. I recently purchased a Beyerdynamic DT770 pro(80 ohms) headphones. I have a x-fi fatality to connect them to. Wondered if the drive bay worked as an amp? I also ebayed a cmoy amp. Never used one but if i don't like it i can always use it for the ipod. Now I was wondering about a more permanent desktop headphone amp but i don't want to spend too much like up to $250.I don't have the time to try to build my own so any suggestions Now this all depends on what they headphones sound like out of the x-fi.
