M,
I would recommend placing a couple of phone calls to Kara @ Dehavilland and Ralph at Atma-Sphere. Both companies amps excel with high efficiency speakers, and both are friendly and knowledgeable enough to explain the pros/cons of 300Bs vs some other good options. IMHO, these are two of the highest credibility people in the business, and they've developed products that are likely to be a particularly good fit for your application.
