I just got a pair of these and having heard all the talk of how "loud" they were i think i may have a problem. Many people have said they can barely turn the volume up to 50% without it hurting their ears. Right now, i can turn them up to 75% easily and at 100% it's very loud but certainly not deafening. I have the Master Volume in the Santa Cruz control panel all the way so it's not that. Any ideas?
