I'd advise against the Denon receiver as a processor. I did this for a while w/ separate amps and a separate 2-channel pre-amp for music. When I got my B&K ref 30 I noticed a HUGE difference from the Denon on soundtracks (and the dolby pro-logic decoding in particular). Not just a slight difference -- quite noticable. If you read all the reviews of the Ref 30 every one of them remarks how great it is w/ soundtracks, and my experience has been consistent w/ those remarks.
