Can someone please give me their input on the receiver I should purchase? I have RBH MC series speakers. I was considering either the Yamaha RX-V650 or the Denon AVR-1905 receiver. I like both of these because they are in my price range and they have the two (2) zone feature I like (given that I have RBH outdoor speakers on the porch). I can't decide between the two. Any experience with either one or recommendations would be greatly appreciated. Thanks so much!
