I'm gonna be lazy here, MM and suggest a little active search on this one.
I had a bunch of posts in the GAS group, and tagged onto a lot of other folks threads.
It would take some time and some reading expense on your part, and I can understand perhaps a desire to condense it to a pill, swallow it down, fart and move on. Personally, like I did on the 'trip', you might even read some things of interest along the way, that you didn't even know you wanted to know....
Quick (!) from me you will get that ALL the exhibitors were just great folks to encounter. When I was getting kinda tired part way thru the day, you could count on an exhibitor to get you cranked up about what was in the room.

Some like Klaus from Odyssey are just plain infectious, and I'm still excited.
I went to hear horns and speakers in general. I wasn't disappointed.
As for intrigue, I implore you read the posts.
I had some great intrigue...I'm still intrigued, too!
Like I said, I'm just being lazy....
