I have gone through and verified that all the components in the VP150 are functioning via the ear test. As for timbre matching between the two M80's - yeah they match and sound great. While running through some of the Avia tones I did move the center next to one of the M80's as I thought maybe the difference was location but it still sounded like the center had a blanket thrown over it.
As for whats powering the speakers, a Denon 3803, and actually I have tested with two seperate 3803's as I originally thought it was a receiver issue many moons ago.
