Best Speakers for 10' x 12' room?

I am putting together a new system for my upstairs office where I do most of my listening and moving the current system downstairs and would love help finding the best speakers.

I have been listening to the B & W 805D with a REL 238 sub & stands, and the Wilson Audio Duette (under 9K for demo model with stands). I wonder about auditioning the Duette 2's, which people say are better, but they are 10K more.
I am also open to other possibilities as well.

I would love to hear people's experiences with any of these speakers or others that work well in a small room. In most ways I like the Duette's a great deal more, but the 805D's were warmer and I am wondering if that is because they were played on Mcintosh equipment. I think of trying the Wilson Audio Duette's with the McInosh amp/pre-amp - Any feedback is appreciated.

Thank-you,
