Thanks for your response John, and for validating what I was thinking that the 2807 shouldn’t have had any problems at 95dB. I’ve also thought for some time that my bad (not subtle but really bad) results with Audyssey were to atypical to for a system operating properly.
Not sure if I mentioned it but Dolby PLIIx also sounds much better on the Onkyo. So much so that I’m using it as my standard listening mode for now pending the myriad other modes available to try. With EQ Audyssey has applied to the subwoofer and the greatly improved soundstage from the PLIIx I can’t see not using them now.
I turned off all the EQ functions when I switched the Onkyo over to test the M80s at 100dB. The comparison is between Onkyo’s “pure audio” and Denon’s “pure direct” both with all EQ and bass management off.
