Matthew2,
Good choice going with Bryston.
I have five 7B-ST THX mono block amplifiers. One for each chanel of surround. KLF 30's for front and rears, with C7 center.
I have yet to disapointed with this combination. Plenty of head room. Neither the amplifiers or speakers are over worked to reach reference levels when the urge strikes.
Heck I get so much bass that I only use my subwoofer as the .1 in digital surround.
Good Luck!
