You might also consider the Bel Canto eVo2i. I have owned several integrated amps in your price range and the Bel Canto is a winner for me. Not sure how it will mate with the B&Ws but it worked exceptionally well with my Proac Response 1.5s. It does have the required balanced input and a pre out, both prerequisites for me.
Just the other day I received an email from a fellow Agon member who purchased the eVo2i after seeing several recommendations. He thanked me for the rec. I thought that was a nice touch.
