What receiver will you be using? I was originally going to build a home theater set up, I just hate running cables. If I ever have the opportunity to own a home or even build a home, I will definitely run the cables in the wall.
I use a Marantz SR-7008 receiver in the living room HT/music system and an Arcam AV40 preamp/processor for HT duties in my main listening system. The SR-7008 used to be in my main system but was moved to the living room system after getting the Arcam.
The Marantz handles all the preamp, processing, and amplification duties in the living room. In the main system, all music preamp and processing duties, as well as all amplification, is done with PS Audio equipment.
