I just compared these 2 units in a dealers showroom with Klipsch speakers. He originally suggested the 3803 but after comparing them, both of us thought the Pioneer sounded crisper + seemed to have more power. We set both receivers on the same volume display (don't know if that is correct or not) and watched several scenes from Men in BlackII & the latest Star Wars dvd. He demonstrated the Denon on screen display, crossover, and assignable inputs. He was not sure about the Pioneer since it had just arrived in his store a few days earlier. Here's where I need some help, please, does the Pioneer have: a macro capable remote, assignable/customizeable inputs, video conversion, on screen display and adjustable crossover? I am leaning towards the Pioneer, but want to make sure it has the same features as the Denon. I want to pair this receiver with the B & W 603 series speakers. Also, I know that Denon has a high bandwidth (100), but what does Pioneer offer. The salesman stated that anything over 37 would pass the signal without degradation.
