The B&Ws like a powerful SS amp with a high damping factor. The Jeff Rowland Research Group Concerto will all handle the B&Ws nicely. My Conrad Johnson CA200 control amp will also do nicely. You didn't mention a budget. Both of those are about 7-grand new, but over at audiogon.com you'll likely find one lightly used for about half that.

X2 on the Rowland, a very musical amp. I think the retail is ,6,000
but I have seen them for 4,000 or so on audiogon.

For much less $, you can go for a used Plinius. You'll get about 150-200 watts per 8 ohms depending on models/iterations, and great bass response & musicality.

Creek has been making some of the best integrateds in the business for years- you owe it to yourself to demo one in your price range. For more money, the Krell 400xi is a killer at every level. Good luck!
