First things first:
I want to congratulate Jude on scooping the headphone universe and hearing these cans a solid 18 hours before any one else. He warrants the honor. I've done my fair share for this hobby, and there are few who I consider brothers in arms for this glorious little world we've built, and Jude is one of them.
The fact that Sennheiser bestowed the honor on him only shows to go ya that Sennheiser "gets it" too.
And the fact the Sennheiser delivered to us the product that will define the full birth and first full blossom of headphonedom as a legitimate part of the audiophile world will only be clearly seen 3-6 years from now, but mark my words, this is it.
I'd love to talk more, but I stand to wear out my welcome with Spammy words, so I've asked Jude, and was told it was okay, to point you to the thread in our vendor forum area for my further comments
here.
Jude, man, I'm so friggen glad you were the first one to get it right between your ears with the HD800. Congrats!
