If you guys have to choose specifically between Vandertseen 3A Signature and B&W 802Well, the B&W of course. BUT....
...Your better bet would be a pair of Vandy 4 or V (used). Better than the B&W 802. Cheaper to drive, too. I mention these because you like the Vandy sound.
The 802 D is a nice speaker but I enjoyed it best when driven by a humongous expensive amp... so, keep in mind that the cost is not limited to the speakers price alone!
