I would like your opinions on these "musical" receivers around $400 to replace an old dying Sony. I am not looking at Denon very seriously because I can't find any authorized dealers selling the 1803 at a competitive price and I feel that the 1603 is not as good. I will use it for music & hometheater (50/50) and it will be connected to a 5.1 setup in a 15x20 room with vaulted ceilings (20ft). I am trying to decide whether Logic7 will be more useful than the 6x80W amps. For H/K receivers othen than the 8000 it is limited to 2 channel input, so the question is if it is that much better for music than a all channel stereo DSP. I am also not convinced on 6.1 as compared to 7.1 and I am not sure I will be upgrading to 6.1. I have N-series JBLs (N-26, N-24, N-center) + 10" JBL sub and as far as my upgrade plans are concerned, I will upgrade the speakers I find them lacking. My auditions so far have been inconclusive, but I am leaning towards the Marantz ... Thanks!
