I know volume is a function of the efficiency of the speakers but I was curious if 45 with my very efficient Klipsch Cornwalls is a bit too high for music. Above 40 it sounds too loud and not as pleasent. I'm listening at 35 to the new Springsteen CD. The Klipsch are very efficient so most other speakers would need a higher setting to achieve the same sound pressure. I guess I need to get a Radio Shack SPL meter.
