If you go (exhibits run 10/18-20), sign up now with code AES143NOW (applied on the last page of signup) for a free pass to the exhibits. Not sure how long it's good for, but it worked a few minutes ago.
The AES show is more geared to live sound, installed sound and broadcasting, but there are some companies with DJ related gear ( I saw Audio-Technica, d&b, KV2, L-acoustics, Neutrik, Sennheiser, Shure, TASCAM, and Yamaha listed) ... full list (as of now): AES New York 2017 » List of Exhibitors and Sponsors
If you live in the NYC area and didn't go to DJ Expo (or just want to spend a day in NYC), sign up for the free pass while it's available .. otherwise it goes to $50 and then $75 at the show .. don't pull a Mix
