I wasn't concerned that an outboard amp might make it sound "worse". I was wondering if its just going to sound the same - with the ability to play louder. If it isn't going to be a night and day improvement I'd rather wait and see what my next move might be (big screen, behemoth sub, dedicated theater, etc...)
I do believe that a salesworn at Circuit City told me that the more powerful amps deliver better bass. Don't know if that's true or not.
You never worked at Circuit City, did you?
