movie theatres won't help you here, movies are different from music by a LARGE degree.

I say cheap so you aren't tempted to say "that'll cost me too much money"

I want you to be able to understand what I mean by "soundstage" before I say, "THIS IS WHAT TO DO TO GET IT"

IF you don't care about soundstage, then i'lll have a different recommendation than if you did care about soundstage.

Maybe try listening to your favourite CD's at a local hi fi sound store on some of their better sound systems and see if you can figure out what i mean by sound stage.

The wikipedia entry on soundstage should help as well.
