I have a pair of TH-X00 PH and a pair of Fostex TH-610 - they're close enough you'll be VERY happy with either. The TH-610 are slightly more polite on interactions between bass and mids.
ZedPottsBut they still remain the headphones I can simply turn my amp up ALL THE WAY without them harshing my ears with treble screams or clipping in the drivers, I've gotten noise complaints in apartments from both headphones. (I like my music on my head loud.)
