You should investigate the Emotiva line of products. Their XPA-2 amp ($799) along with their USP-1 preamp ($449) would probably work *very* well with your B&Ws and are within your budget.
If you do not need as much power as what the XPA-2 offers, Emo has a smaller amp, UPA-200, for $349.
All emo gear comes with 30 days trial and a 5-year, transferable warranty...
