I would look at a Rogue Audio Sphinx and I would roll in a set of NOS Mullard driver tubes. This will deliver plenty of power to handle the B&Ws, the Mullards will add a bit of warmth and will deliver wonderful detail and a great listening experience.
The stock tubes stink and this amp will be too bright for your B&Ws with them. These would work brilliantly:

For $2K or less, this is my favorite amp and think it will outperform most, particularly with the tube upgrade. If you haven't messed with tubes previously, it is no big deal to swap them out. Easier than changing a lightbulb.
I am not a Rogue dealer and have no affiliation with Rogue. I think they make a great product.
