I know the calibration currently is less than ideal for these speakers and I think the Sony is struggling with the different ohms of the VP180 and the M60. The M60 are light in volume compared to the VP180. But then, the VP180 puts out a lot more volume than the VP100 did so I think it is over powering the M60's right now. Even though the M60's are putting out more volume than the M22's, I don't think it's as much of a difference volume wise as it was between the VP100 and the VP180.

I was reading the manual for the Denon 6500 and I know is specifically said that if even one speaker was 4 ohms and the rest were 8 ohms, that you needed to set the receiver to run at 4 ohms. The Sony doesn't really say anything. I don't know if that would have any effect on the VP180 or M60 output either.
