Oh don't get me wrong... I think your assessment of the HD800's based on what's been written here is probably spot-on. Clinical and maybe more 'neutral' is how I might put it (again, I've never heard the HD800's), but I'm just being a picky jerk about the semantics. You and I may be meaning the exact same thing. Where I equated 'accurate' with 'natural', I think you were using it to be 'transparent to the source', which the HD800's just may be. The D7k's are not transparent to the source. I think they are warm and rich and coloured. But just a little, and in a way I really find very realistic. 
Amazon and Buy.com both have them for $678, but may not be 'authorized' dealers. You are correct that just about everywhere else it's closer to $1k. Ugh... And you are right, nothing in the FS forum.
You might want to put up a WTB post and see if that get's you something.
I love these D7k's. I'm listening to music I've lived with for many, many years and they all sound fresh and new and punchy and amazing. But $1k is steep, and I'm not sure I'd pay that.
How patient are you?
