I have a Yamaha 2500 receiver and I want to switch to inwall speakers. I have yamaha ns777 tower's and want to get some inwalls that will come close to the quality of towers. I have heard the Polk Audio LC80's and like them. I just stumbled apon the Klipsch 5800's. I haven't heard them yet though. Anyone have any suggestions on either one or maybe some others. I'm looking to spend $500 or so for the fronts and $300 or so for a center channel.
