I don't understand why. From most impressions, it would seem the HD800 is like the 60 but better in some areas. In the long run, I'd imagine the HE-60s might be preferred by some. I know the newness of the 800s seem to have caused some to go overboard. Yes, I'm thinking out loud and not really making sense. My coffee hasn't kicked in yet.
In a way, I hope you're right. I would like to see the non production cans hold their value regardless of the new stuff that comes out.
