My VP100 (and, to a lesser extent, the QS8s) sounds different from my M60s when running receiver test tones but sounds much closer when running real world signals OR a test CD.

As far as I know, the difference results from the fact that the receiver test tones are injected downstream from the bass management, ie the different rolloff frequencies will make a big difference in sound when running test tones BECAUSE the subwoofer is not intercepting and reproducing the lower notes on the center and surrounds.

I'm not 100% sure this is the case but it sure sounds that way. Does anyone know for sure ?

EDIT -- Just to be clear, you may still have a defective VP150. Things like that do happen from time to time. I did find a difference, however, between using receiver-generated pink noise and using pink noise delivered via DVD.
