Second the recommendation for different speakers with either the 805 or the 211fe. But, whether or not it’s a good technical match or what anyone else thinks, if you’ve been running the B&Ws with the 805s for 15 years and like the combo to the exclusion of other gear, maybe it just works for you.
Seems you prefer tubes, but another consideration along Nordic’s line might be a used set of 500MBs, if you really like Cary-ish sound. I recently picked up a pair, here. They are said to be voiced/sound like the 211s. I think that is very much an overstatement, but they certainly have a hint of that flavor. I suspect they would probably work better than the 805s or 211s with the B&Ws, as would probably most any other decent medium to high power SS or hybrid amp.
@sbank and OP. I’ve heard lots of stories about "changes" in Cary support over the past few years, too. I was worried about that when I had an issue with a recent new amp from them. In the end, a little frustrating, but they made it right.
Edit: OP, I see from another post you went with the 211fe and started rolling tubes. What did you decide with your speakers?
