Sargatanas, according to your sonic preferences, Fostex TH600 might disappoint in some ways: 1) You will probably find the mids to be recessed if you're looking for "in your face" headphones. 2) Denon AH-D7100 are simply more bassy cans. But quality wise, TH600 is definitely a winner here. 3) TH600 tend to be on a bright side. Anyway TH600 are nice metal cans combining fun sound signature with great soundstage and resolution.
