Still undecided what to replace my Bose 321 with . . . Sony Receiver vs Denon (prefer $500 max.) SVS 5.1 vs Klipsch 5.1 vs Polk 5.1 vs many others $1000 plus or minus max.) Prefer a system best for music, but good for home theater! New receiver must work both TV and projector in same room, but not at same time! Any and all advice will be appreciated!
