This to me, still sounds like a good reason to not recommend Yamaha for M80's as I do not experience anything like that with either of my Denons.
I agree. At least not by itelf
I'm really happy though it worked out this way for me. It has help me understand one of the reasons why people purchase separates as opposed to having a "all-In-One" solution receiver. Perhaps if I chose the M60's with the 8 ohm rating the Yamaha would have sounding more appealing to me. All I know, for me, this has put me on a new path of using separates here on out.
