Here is what I have: ML Vista fronts, Motif center, ML montage surround and I am using Rotel RSX-1067 receiver. My room is 16' x 18' . I am looking to get a used Rotel rmb 1095, Sunfire cinema grand or Cary Audio cinema 5, all at 200wpc @ 8ohm. Will adding an amplifier bring out my system or am I wasting my money? I listen to 2 channel music sometime but mostly watch movies, any imput is greatly appreciated
