Hi
Not quite the answer you may want but I am using the Marantz with a Sony DA2400ES receiver. I am using Atlas Equator interconnect with a Tacima Mains Conditioner and Clearer Audio Copper-Line Alpha mains leads. My speakers are Monitor Audio BX2 with Chord Company Carnival Silverscreen speaker cable.
I did change from a stereo amp because I'm bit of a minimalist. I find cd playback superb and having listened to my cd's through other stereo amp set ups I dont think I have lost anything. In fact I love the sound. It's clear, sharp and has plenty of bass when needed. Of course thats just my personal opinion.
Reviews of both Denon amps state how musical they are so I don't think you'd be disappointed. But I suppose it would also depend on your speakers etc.
Hope that helps a little.
