Our TV died so we bit the bullet and bought a 52" Sony, the deal included a PS3 that is a blu-ray player. I want to up grade our home theater package with a new cd player and speaker system that will be compatible with the PS3. I don't want to spend a ton of money but I don't want a piece of junk that sounds terrible. I also don't want to fish wire through the house to hook up rear speakers. The room is about 20x 40. Suggestions Please
