Boy, we seem to be responding at the same time! Thanks for your help. Mine is the 1802 (80W) model. All three manuals mention that they have a protector circuit that may be activated if speakers below 4ohms are used... which tells me that Denon doesn't think 4ohms would be a problem. I have heard mention by Ian on a few posts that the M80's are so efficient, that the 4ohm rating really doesn't effect "most" receivers. That was one reason I was considering the M80's.
I really appreciate your help. You're making it easier to make a decision.
