I have in-wall/in-ceiling speakers: B&W Sig7NT - 1 7" mid/bass, 1 1" tweeter, Freq. Resp. 40hz - 25KHz; Sensitivity 88db; 8 ohms (front left and right) B&W CCM 80 - 1 8" mid/bass, 1 1" tweeter, otherwise same as above (rear left and right) B&W CMC CC - 2 5.5" mid/bass, 1 1" tweeter, Freq. Resp. 65hz - 20KHz; Sensitivity 88db; 8 ohms (center) I have been contemplating getting a 5 ch. amplifier (maybe the Sherbourn, Rotel or Parasound). I believe that for large, floor standing speakers, the increased power from a seperate amplifier will definitively improve sound. BUT, with my smallish, in-wall speakers, will I see significant improvement in sound from a seperate amp, or am I just getting caught up in the HT thing? Will I get the same sound/performance with a receiver?
