I just got my m60s in this weekend and love them. I have been listing to all kinds of disks running through my Denon 3801 with treble and bass set to 0. I listen to a lot of live (mainly soundboards of Widespread Panic, i have over 300 shows) and wanted to know if you guys turn up your treble. I have read that most everyone leaves treble and bass on 0 but do you ever turn it up. Do you just let you ears decide depending on the disk?
