Sup fellas, I've been looking at buying an Onkyo 809 receiver (to replace the current yamaha) to help set the foundation of a surround system. Got some noob questions though. 1. Will bi-amping (since the receiver is capable) help the front towers (RTi12s) as far as bass output and just general music listening? 2. When I watch a movie, will bi-amping mean my front towers will over power or just be louder than all my other speakers like the center and rears?? Will it be unbalanced I guess is my question. Fill me in guys! The more info the better cause the sounds like a good way to go!
