I'm going to be picking up a Denon 3803 in a couple of months, and I'd like to get a couple speakers to utilize 7.1. Currently I have the Polk RM6600 sat/sub package and I am happy with it, however I can see where more mid-bass would be helpful. I'm thinking about adding a nice pair of floor standing speakers to this set up, and sliding my fronts now to the rear. My question is whether I should stick with Polk for the new fronts or if another manufacturer might be better if I've calibrated correctly. I've heard some good about Paradigm and Klipsch, but will they sound good if matched with a Polk RM 6600 and run through a Denon 3803?
