I'm seriously thinking of doing this. I'd keep my Yamaha as a processor, and have two fronts and two rears. I'll make a decision on whether a sub will be needed when I've started and had it up and running.
Thing is, I'm not ever so clued up what I need to do.
Im guessing RCA cables from the corresponding outputs on the Yamaha to the speakers. I would then re-run the room calibration ?
BTW I'm very happy with y MA set up so it's not a done deal.
