Help with BW vs Def Tech

[Cwb1]

I currently have my finished basement which will have 5.1 surround set up for my movies and some music. My upstairs living room will just be dedicated for music. I have Def Tech 350 book shelf ( with sub) as well as BW 683 floor standing. Any opinion on which I should use for the home theatre set up and which to use for the straight music? Thank you in advance for any help/insight

In terms of accuracy, I think the SM350 is a lot more accurate. The Audio Critic reviewed the SM450, and its frequency response was very accurate. The B&W is not as accurate (HTM review).

I think the SM350 + sub for music and the B&W + sub for movies.
