Right now I have a Rotel RB-1090 running a pair of Polk LSi-15s, I plan on buying another rotel amp to power the center and rear speakers. So what I've come down to is the fact that I need a receiver or preamp and while sound quality and reliability are priorities, power output doesn't matter at all since the receiver won't be powering the speakers except through preamp outputs. I don't mind spending a decent amount of money, but I want to make sure that my money goes to good use. In other words if there's a 600 dollar receiver that sounds 96% as good as a 1500 dollar receiver, I'll take the 600 dollar receiver. I'll be using this for both music and movies, and honestly having the latest greatest 6.1, 7.1, etc sound format doesn't really matter to me as much as just having clean clear sound with good imaging.
