x2 on Pantera - Becoming, my subs can't keep up with the double kicks though
I listen to mostly rap but I'll have to say rock takes the highs/mids much better, here's my fave SQ's.
Kansas - dust in the wind
Goo goo dolls - long way down
Deftones - passenger
Steve Miller - blinded by the light (great guitar solo)
The ending of Pantera - cemetary gates
Most Pink Floyd songs
The Chronic 2001
DeadPrez RBG for mids
Most Tool songs
Pac
