I am looking to purchase a 7125 and bi-amp my Polk Audio RTi10 with it and use the rest of the channels for my 5.1 system. I have a relatively small room 19'd X 15' w, actual listening area is 12'd X 12' w. I can not listen to movies or music loud because of my family but I am looking for better quality.

First of all, is this a good idea?

Other than Y-splitters do I need anything else for the Bi-amping?

Would I be better off purchasing 5 2200 monoblocks.

I like the cost of the 7125 and the simplicity of the hook up of the 7125.
