Looking to enhance my 60" Mits DLP with a sound upgrade. A multi-channel surround setup is impractical for me as I am completely deaf in my left ear. My right one still works fine (thank the Lord) and wants the most of everything from the music of "Mamma Mia!" to the stomach thumping warp jumps in JJ Abrams' "Star Trek". Looking to stay under $300. Any models I shoiuld be leaning toward?
