I just got the Denon receiver back from my sister and hooked it up to the M60's. There is a definable difference in sound quality. The upper frequencies are much clearer...cleaner if you will. Mid-range is improved as well. Overall the speakers also seem better balanced than with the Technics receiver.

I remember back when I first bought this receiver in the very late 1980's. When I replaced my Sherwood with the Denon I had the same experience. I could immediately tell the quality of my listening would improve.
