I am putting together a new home theater system with RTiA7 fronts fxi4 surrounds csi4 center and a dsw500 sub. My TV is an XBR Sony LCD and I have the Sony 350 Blue ray player. I need a quality receiver to control this whole system. Staying with Sony would be nice because of the Bravia Theater sync that allows one touch control across components. My question is does anyone know if Sony's ES receivers are powerful enough to work well in such a system?
