SF Signum vs B&W CM4

just went to my local hifi store - but they only had the Signum to buy not to demo (typical Hong Kong thing).
For a similar price they did have the B&W CM4 - now they are sleek and sexy floorstanders and would fit in with my idea of small.
2 q's
1. How do they compare vs Sonus Faber Signum for music?
2. what about for movies if say B&Ws are fixed up with a CC6 and LM1...and then the Signums are hooked with the solo.

(rest of system is integra 9.1/onk989 and most likely the Arcam DV27)

The B&W has metalic dome tweeter, the SF silk, some people prefer silk, smoother, less harsh, most audiophile speakers use silk. Also the SFs are well known by the quality of reproduction of acoustic instruments and voice (best mid-range), the B&Ws might have more bass and treble, but will also be easily harsh...

This is a very general guideline, in the end you must audition both to decide...

Not to mention how beautiful the SFs are, handmade, solid wood, real leather...
