First I never heard the Ushers. In my personal opinion the B&W's would be best for HT but not for 2 channel. They are forward and punchy. For 2 channel they will most likely give you listeners fatigue in the long term. That's why I didn't get them. The Sonus faber is very nice but just a little too laid back. While I was still in the market I heard Dynaudio. That was the only speaker I ever heard that I HAD to have. Yes I got the C1's. Tried to upgrade to the C2's but my room is too small. Your room is a great size. In fact I would consider stretching your budget a tad and consider the C4's (my favorites to date) because of your room size. I like the Dyn's so much I did upgrade to the signatures and couldn't be happier.
I can never recommend enough to try and listen for yourself - after all it's your money and ears.
Good Luck
