I have a Headroom Home, the same model on Audiogon, that I got off ebay for about the same price. I use it with the Sennheiser HD 650, and it sounds pretty good. At first I wasn't very satisfied with it, sounded bright, bass wasn't very strong. I was using a PS Audio Ultralink dac and Kimber Kable PBJ cables, then I switched up the cables to Black Mountain Gold Peak ic's, it made a world of difference. So I guess you just have to make sure what kind of cables/source you are using, because this can make a big difference in the quality of the amp. This amp sounds even better with Sony CDR 3000's. Anyway for that price you can't go wrong.
