B&W CM6 towers with a Sonus Faber center??


Help!  I have a pair of B&W CM6 Towers (and an REL sub) that I use both for music and TV.  The B&W's are fine for movies, but a bit too bright and mechanical for my taste in music (and the room, which has tile floor).  Have been kind of kicking myself for not buying a pair of entry level FB towers instead of the B&W's.  Recently, I was thinking of adding a center speaker to my system both to improve the TV audio for dialog clarity and overall sound experience.  I was wondering whether an FB center speaker might be effective way to temper or compensate for the brightness of the B&W's, or whether the pairing would be incompatible.  Does anyone have any thoughts or opinions on this?  In case this helps your analysis, for amps, I have been running an ancient Yamaha AX700U which I adore, but am in the process of replacing it and am considering a Yamaha RXA1070 or RXA2070 so that I can finally move into the modern era for steaming music. It also runs a pair of outdoor def tech's on the back patio.  Any thoughts or advice any of you can provide would be really helpful.

You will not improve anything by adding center speaker, Yamaha and B&W both have bright sound in general, and adding center may improve a little the TV audio but will be a disaster for music .
My advice is to buy decent integrated hi fi amp (not a receiver! ) and replace your speakers to other brand .
The absolute best multi channel system is to use all identical speakers. This can rarely be done, so the best compromise is all timbre matched. Using different brands is definitely wrong. Take a look at this article. It’s focus is on matching front and rear, however matching front and center is even more critical.

Here’s another good read,

What is your source for playing music? Could it be causing the brightness? It just makes common sense that if the speaker was the problem, it would be bright on everything.
