That is interesting. I'd like to see it matched at 95db as I think that is nearer the "real" sound volume and presents peaks well in excess of what some amps will control.

But, I do concede that even at 75db I'm very surprised (and skeptical) about the test results. Again, just comparing my Denon to my separate amp, there is a quality of sound difference. Not "warm, or bright or blue or green", just a very obvious harshness on certain male vocals and horns and some guitar notes that does not occur via the separate amp.

Anyway...
