Hi all, I have a Marantz SR7000 which I love the sound of. I recently finished my basement and am using it for my HT. I had the electrician run wires outside to my deck in preparation for installing some outdoor speakers. I'm getting ready to install the speakers and realize that the SR7000 does not have A/B switch, or even alternate speaker posts, just multi-room. Am I better off buying a 2 channel amp for the outdoor speakers, or take the plunge and buy a newer receiver that does have an A/B option? Thanks, Ian BTW, the receiver was recently paired with Def Tech Mythos.
