Yes, quite worth it! I wish I made more time for dinners and hanging out, and for some of the top gear that I missed. I think I was rather focused on short term tasks, knowing I am not budgeting for a killer headphone rig. But the chance to hear prototypes and multi-kilobuck 'phones is rare. I seemed to get there too late each day to cover as much as I wanted.
I did have a chance to get to the 2ch exhibits, although I rushed through them. Most were not exactly impressive on an absolute scale of realism, but the gear was cool and many demos had very good qualities that came through despite the room problems.
I must say, the huge Wilson room (with a view of the pool) had the most realistic reproduction, but Wilsons are not new to me so no big surprise.
I also attended most of the panel discussion on mixing and mastering. What an illustrious panel. I was delighted to see Keith O. Johnson there, someone I'm very familiar with over the decades, who according to a co-worker had not been scheduled to attend. He's 75, a runner for exercise, and in great shape. His comments are always illuminating and thankfully he goes on longer than his fellow panelists want, but shorter than I want.
Thanks again to all who shared their gear... I got a lot of tangible value out of that, as well as fun.
PS: health held up well, although my ability to make coherent sentences went south now and then. (This week I'm getting x-rays on one tumor (should be successful), looking at surgery on another (again, easy to get at), and chemo to help with both and with the unknown. None of this bothers me terribly much, not compared to the general, uncertain, scary/horrific part that perhaps most of us will go through eventually in some form.) Not feeling sorry for myself... just having fun and enjoying the music!
