I bet it's going to be great -- wish I could be there, but I'll probably still be in Germany.
My suggestions for the name, should "CanJam '09" not be the one:
If there's something as amazing as the Millett 307A setup at this one, you could call it "PhoneMoan '09."
If there's a wave of high-end Koss KSC-35s that debut between now and then, ClipTrip '09 would work well too.
Or maybe LA Headphone Meet - L'Internationale '09.
Or in that vein, maybe The Fourth International.
But best of all, if the next one is in Boston, that one should be called:
THIS IS BOSTON, NOT LA (2010).
