Look people, I'm glad you had fun with this little test, but i just finished my application to the "flat earth"...I mean "amps don't sound" fraternity. Don't get me confused again! How can Peter hear a big difference b/w the Pioneer and the Onkyo or Jay hear a big difference between the Denon or the Axiom if there is no difference without more than doubling the power???????
Perhaps the Axiom does quadruple the power of the Denon? And Peter clearly has issues - how else do you explain the patience to swap AVRs time and time again for our benefit? Something is not right here. I'm starting to think my wires do make my system sound better than tin lamp cord. It's all slipping away...and I had it so nicely wrapped up. Time to pull the crystal changer out of the closet.
