Of course these changes make for an unsettled pre show feel, but I predict there will be plenty to see and hear. Can Jam in a tent may not be a bad thing - that is what it was at Newport Beach for several years. I think that the headphone world is now advanced enough to warrant individual rooms and a quieter evaluation environment than the big open ballroom.
CanJam 2009 in LA was a special event with it's small rooms and big hallways in which to stand and talk.
I am still planning to go, learn, and most importantly talk in person to the audio builders I respect and whose equipment I use.
