My current system consists of a Mitsubishi 55 inch with Dvi input and a Dvi remote controlled switcher to run my Samsung HDTV receiver and my Denon Dvd 3910. I have the Denon 3805 receiver. Speakers include Klipsch Rp5's for mains, Rc-7 for center, Rs-3's for sorounds and two Rc-3's for my rears. I use a Nht sub with the dual, non-ported aluminum subs and seperate crossover and amp components in my audio rack. My question is whether it would be worth it to trade in my rs-3's for rs-7's? Sacd and Dvd-audio sound breathtaking but I know that the sensitivity and range of the rs-3's are less than the rs-7 and I feel as if I don't hear much from the rs-3's. I used the microphone that came with the Denon receiver and it did a good job of equalizing/delay/adjusting the speakers in general but I don't feel that the rs-3's are giving me all that I could be getting from sorounds. Any advice?
