I am building a house in which I have installed a nuvo 6 zone speaker system. I would like a multi zone receiver to use with this system so that I can use multiple sources in various rooms or areas of the house. My current Yamaha A/V receiver only supports one zone and will probably only support my HT in my living room. My budget is around $400-$500 and I have looked at the Yamaha Rx-V750. Any other ideas or suggestions???
