Interested in a pair of B&W 802D Audiogon notes re

Where can I purchase new at a retail price Audiogon Bluebook lists as $12,000. for B&W 802 Diamonds?
The N802 8000.00 per pr. were replaced by the 802D which were 12000.00 per pr. The 802D are not current. They are replaced by the 802 Diamond at 15000.00 per pr. So, you will not find a new pair of Diamonds for the price of the 802D. They are different speakers.
