If you can swing it, I would suggest going with the C208 or higher. I understand where you are coming from regarding surround music, but about 70 - 80% of a film's soundtrack comes from the center speaker. I mix films occasionally, and in all cases, films are mixed with identical speakers LCR. There is a perception that only dialogue comes out of the center speaker, but in actuality music, explosions, gunshots, etc. all come out of the center speaker too.
I am running the Voice2 with my Salon2s, and it's a pretty seamless experience.
Here are spins of the speakers you are asking about
To illustrate my point about movie soundtracks, here are some screengrabs of actual movie mixes. They are arranged in the following order: Left, Right, Center, LFE, LSur, RSur. You can see that in action scenes the center is still the most active speaker:
INDIANA JONES - CRYSTAL SKULL - Cliff Chase:
STAR TREK (2009) - Enterprise goes to warp:
Hope that helps!
