YeaI know technically its not a third zone, but would be three seperate areas on zone two. Its actually a decent receiver,Denon AVR 486. Only 3 years old. I figure it would be cheaper to buy a receiver on CL than to buy 2 2channel amps.
Im going to have several wires running along the wall in a cable hider.
3 ethernet (2 will be hdmi to cat5)
This is the reason im possibly splitting, so I can reduce wires. Btw u mentioned noise/hum....which wire...
