Bryston definitely makes super gear with an unbeateable warranty. Given your description of room and speakers, however, I would be concerned about the Bryston's tendency toward brightness - - the B&W's are not known for being laid back and your room is highly reflective.
To my ears, the Creek has more finesse on the top end and may make for a better match. Another worthy Brit contender is the Musical Fidelity A300, which sells for exactly the same dough. Both the Creek and Musical Fidelity amps are available from audioadvisor.com with a 30 day trial period. I'd try both and keep the one that tickled my fancy.
If your heart says Bryston, then buy one used and resell it if it doesn't meet your needs. I've seen this amp recently for as little as $850 here on a-gon. Good luck.
