David,
I recently checked out some Revel F50a and the matching c50a center at a local dealer. They sounded awsome. But for some reason my dealer talked me into listening to the concerta series for a fraction of the performas price before making up my mind.
And trust me the F12 for $1200 are unbelievable. They are no F50s but close.
I ended up getting a set of F12s and the C50a center instead of the matching c12. The dealer had it on clearance and I could not resist.
I set them up at home and they match very well. The C50a simply is amazing. Great dynnamic with no coloratin what so ever. The F12 don't embarass either.
I am sure the C12 would've sounded good too, but I just thought I 'd go all out since the center is the most important speaker in any theater system, and trust me, that was the best decision I ever made. Maybe someday I might get the matching F52a if I finder a LOT cheaper, but for now the F12 look more like it for me for a while.
I also listened to the paradigms and the B&W and believe me, they don't come close to to the F12 even the ones that are twice as much.
I give the revels 2 Thumbs up. You would not go wrong.
