Just installed the last two channels in my 9B-ST-THX, and while putting back all those S-1 screws I wondered if there was an offical N-m torque number that Bryston uses? I do have acess to an appropriate torque wrench from work and figure I could geek-out. This is a also a genetic issue (my Mom calls it the 'G* Method': "If a little strength won't do it, then a lot might.") Needless to say the guys in our family have a habit of breaking things. Though from work I've learned to do the standard hand tight-snug that works best.
