Im sure this may be a dumb question, but can mix matching be a problem? I may be having a problem with the supply system concerning Anthem. I can get the MRX1140 (pre-order) in February it appears, but their 3 channel amp not so much. I was looking at the Parasound A31, 3 channel to hook up to the pre-outs in the receiver. I am also open to another receiver at this point. My goal is to simply acquire something very nice by the end April. Looking for options here
