I had a Denon reciever-avr 85, and Polk rt 55 speaker combo. I remember thinking that the overall sound was thin-insubstantial, and not very exciting.I felt I really had to crank the volume. Later, I used the same Polk speakers with a Denon integrated amp and the results were much better-much fuller sound. However, the polks had a strange,detached, if not flabby sounding bass. I dont know how to explain it, except that it seemed all the low frequencies were inordinately separate from the rest of the music.I was always checking cables to make sure I had not hooked them up wrong. I am certainly not criticizing Denon recievers or polk speakers, as I suspect there was a lot about speaker set up I did not know about back then that may have improved the sound produced of that combination. I would say you would do best to try to listen to them together if possible. Those same polk speakers ended up with a pioneer receiver at a friends house, and she swears by that combination.
