Anyone Hear the New Nautilus 800 Yet?

There's alot of "buzz" starting up and alot of hearsay and second hand comments. I know of several dealers with the speakers now on order, including my local dealer, however I don't know anyone who has heard them.

Has anyone heard the new B&W Signature 800 Nautilus yet, first hand. What were your impressions, and what type of electronics were used?

I holding off a speaker upgrade until I can include these in my evaluation. (Eidelons are my current front runner.)

Thanks in advance.
