I'll be the first to mention this to you, Bose is not looked upon favorably around here, at all. Firstly, they are severely overpriced. Secondly you can do WAY better for $2k, I mean WAAAAYYYY better. I'm not nearly as good as some of these other guys at suggesting systems, so I'll let them take over from there, but I thought I would warn you of the Bose hate that is likely to follow soon in this thread.

PS you may want to ask the moderators to move this into the correct category, more than likely general AV or loudspeakers.
