Ow ow ow ow ow ow.

-15 on my H/K is painfully loud. No freakin' way I'm putting it at 0!!

I think you should set one of the speaker levels at 0 (such as the left front) and then set to volume to the point where it's reference level on the meter for that speaker. Calibrate from there. Otherwise all of your speakers are going to be at -10 and -9. Or your ears will be bleeding.
