If you need the power, then the 7BST is the way to go. I had it before I moved on to the Pass X-600. It was an excellent musical (as well as powerful) amp for my B&W Matrix 802s even if it lacked the ultimate in tonal refinement that the Pass provides in spades. I believe the Bryston products, because of their incredibly generous warranty of 20 years and workmanship, do keep their resale value well. I found that to be the case when I sold mine.
(I listen to mostly classical music, if that is relevant information for you.)
Best regards.
