Well im gradually weeding out my bose lifestyle 12 system. It will soon be the reference series 7 klipsch's. Right now my setup is a denon 3802, svs 20-39pci, and the rest of the speakers are the bose cubes that came with the lifestyle 12 system. I just ordered my RC-7 and it should come in next week. Will this make a noticable difference? I will be getting the fronts and surrounds for my birthday. And then my whole bose system is gone!!!!!! put it up for sale on ebay. dont rag on me about bose, when i first got into hometheater i did not really now anything and the bose system seemed to be great. Until went to a real stereo store and heard what real speakers should sound like.
