I'm going to be moving towards a 7.1 setup, and I'd like to upgrade my speakers at the same time. Currently, I have the Polk RM 6600 satellites with the Polk 350 sub. I plan on picking up the Denon 3803 shortly, which then leaves me with the "chore" of moving towards 7.1. My primary goal is to move towards a 7.1 setup, but I'd also like stronger mid-bass than the satellites can offer in the front. Would simply adding the Klipsch RF-3II's to the front throw the whole system out of wack, or could it be done until I am able to upgrade elsewhere? I thought of moving towards some of Polk's larger towers, but since the word on a Klipsch/Denon pairing has been so strong, I wanted to check that out.
