What audio expos are worth going to?

On the off-chance that expos, like CES actually happen in person this year and next, I was wondering if anyone has attended particularly great, annual audio expos. I've never been to any and with the lack of audio stores where I live, I feel like I've been living in a vacuum. So, I'm anxious to hear a lot of the equipment discussed in this forum. I'm in CA but given the audience, the expos could be anywhere. And conversely, did you ever attend an expo that you would not recommend?

It’s been a long time since I’ve been, but there used to be a CES in Las Vegas in January, and one in Chicago in June. Not even sure if that’s true anymore, but there is one scheduled in Vegas January 5-8, 2022. Covid vaccination is required.

What you used to find is a huge convention center full of the most recognizable consumer brands, then a much smaller venue away from the "zoo", with many of the high end companies. The high end portion of CES was much more intimate and you could talk with folks about their products (often the designer/owners), and actually hear some of the gear...albeit in a not ideal sounding hotel, suite, or conference room, but was far more useful than trying hear something in the main convention center.
Capitol Audiofest in the DC area has become an excellent show not sure if it will happen this year or not likely not.
