I will receive my silver Rotel RSP-1066 tomorrow. Will use it with my Rotel RMB-1095 (5X200). But I got 2 surrounds and 2 back center speakers (Paradigm Studio-20). I'm hesitating between the Rotel RB-1050 (2X70) or the Rotel RB-1070 (2X130) to drive those 2 back center speakers. I'm leaning toward the RB-1050, because for back centers, I think that 2X130 would be overkills. What do you think??
