Hi! I am running a Yamaha DSP Reciever with DD and DTS. I run seperate power amps: Bryston 6B SST for the fronts and a NAD 2600A for the two rears. I also have a powered sub: Velodyne Servo F1500. I am looking for three fronts(L,R,CENTER) and two rears. I use a Sharp Z10000 DLP Projector so shielding is not critical. My old and dated Polks are just that. I like the idea of B&W or Definitive Tech with bipolar rears but would like to hear all your opinions. Thanks! "The beauty is in the details............"
