Welcome to the club Elizabeth. (Bryston's VP has already welcomed you here).
You are going to find that in addition to outstanding performance, in the unlikely event anything should go wrong, even many years down the road, that Bryston's after sale service is completely unmatched -- even for minor cosmetic issues, they stand behind their gear (on my 10 year old bryston preamp, some of the silk-screening was becoming easy to rub off -- so they replaced the front panel with a new one -- try to find any other manufacturer who will do that! There are many other people here who can report similar experiences with James and his crew. You just can't give your business to a more deserving outfit than Bryston.)
Your new setup is very similar to mine (I have a new 4B SST2, and older BP25 and a BDA-1) It sounds amazing. You have many years of enjoyment to look forward to.
