Hi Matthew, you've gotten lots of great advice already, I'll just chime in that I recently got to hear the new 802D3 and the Olymica III - not the exact speakers you're considering but close enough that it's relevant. They're just too different for you to pick without hearing together.
The Olympica had a luscious midrange, so smooth and sweet and pretty. But there was very little low-end. If you said you were a classical/acoustic/jazz listener, I'd tell you to run to your nearest dealer and buy the SF. But if you love to crank The Clash or Zeppelin 2 quite often, I don't think the SF is the speaker I'd pick. The Wilson Sabrina may be even better than the B&W and SF, I've just not heard them yet but hope to soon. Point being, to my ears, two of the four speakers on your list are not at all interchangeable - they're very different. Like tiramisu vs. trifle!
