I'm in the market for a good home theater / music system.

I plan on putting this system in to a large game room--roughly 20 x 40-- and I like to listen to music as much as watching movies.

Is there really such a thing as a speaker that plays movies as well as music well?

I currently have a B&W700 series system with a B&K ref 50 processor, Rotel Amps. I really like the system, but I do not think the B&W speakers do well with movies or Rock n Roll type music(I do think they are excellent with Jazz, Classical and soft rock, though).

Does anyone have any good recommendations on a system that plays movies very well but is also musical? Does such a thing even exist?

I have been saving for while and I am willing to pay for good speakers. I will probably stick with my current processor and amplifiers for the time being, but I am open to recommendations for these as well.
