There are a few LSA Statement hybrid integrateds on sale on Agon at the moment - tube pre- and duel mono solid state output. They're rated at 150 watts, but doubt you'll be using that much power.
The Atma-sphere M60 monos listed will also do well with the BW's. As will the CJ LP125 monos also listed.
