I know that my current Denon/Axiom/Pio 141/Oppo combo looks and sounds a lot better than the integrated Yamaha sound bar that proceeded it. By a lot. And that sound bar was a big upgrade over my old Yamaha receiver and Bose satellites. By a lot. The only constant has been the room. So, am 100% positive that I have upgraded how things look and sound for the same 12x17x8 room.
Glenn:
Unless I'm misunderstanding you, no one is arguing that there will be huge differences in changes such as you made above. The argument is that the changes were due to the speakers being different, not the electronics (at least once you are using "reasonably good" electronics).
FWIW, I think you make an excellent point regarding the featureset of different electronics affecting the sound through audysey and the like...
