B&W 805D

Is that not the Signature Diamond you refer to? A two-way floorstander? It's on their website...

Find a dealer and wire him $20,0000. as a deposit.

I couldn't find a 805D on the website. Found the 805S but that doesn't have the diamond tweeter.

I would be worried that they would be too fatiguing to listen to...I guess if you had "warm" equipment it wouldn't be too bad, but you would have to be careful. I have heard all of the diamond speakers and they seem pretty balanced, but once you cut out the lows, I am not sure what to think...I guess I would just have to hear them!

Not in the current form of the 805.
