I am interested in a stereo receiver to run 6 sets of speakers 1 sets for outdoor, 2 for indoor and 3 for basement use. I care mainly about music rather than video. I'm thinking of using a speaker selector monster ss6 (this is the highest selector wattage I can find, also for volume control reasons).
Can anyone tell me what the appropriate size wattage, or which actual receiver should I use for this application. Also should I buy a pre-amplifier to add power?
