The great thing about today's tech is that with the right speakers, and electronics, you can get full enjoyment from both music AND movies with one system. (Yes, I know many people still have separate systems, myself included - but honestly it's more because of the hobby aspect of this compulsion than true need.)

I got a little foggy when you began describing what you've currently got. At first I thought you had four speakers in one room...but now I'm not sure. Do you have two separate rooms?

What is your goal? If indeed you do have a dedicated room for audio, is that room going to also serve as your HT? (dvd's, TV, etc...?) or is that room going to be without sights...just sounds?

If you have two separate rooms that need upgrading, I'm guessing you have the audio only room, and then the usual livingroom, no?
