I have also heard several of the new 800 series at AV Therapy in Nashua NH (now my default dealer for everything audio-video, BTW) and came away very impressed. The description given by class a does hit it pretty good.
If (when) I shop for upmarket speakers, it would be tough choices there. With the KEF Reference, B&W 800 D3 series, and all the other brands they have setup to demo (far more than they list on their website) it will be multiple visits and a couple of home demos to decide. At least I know with that dealer, I can take home anything they got on a handshake and come back with the product or the payment when done testing. And I have done just that with many things.
