I just found this Stereophile post that talks about these audio shows:
I attended the Newport show for many years but this year I'll be going to the June show at LAX -- if you check the list of exhibitors for this show you can see all the main dealers and brands will be present whereas for the September show (which btw will be in Anaheim so not Newport by any stretch of the imagination) there are no exhibitor lists available. The LAX location is easy to get to and was a good hotel back in the day that Stereophile used to run a show there so I've got my tickets for June
FYI: Copy of an email I received regarding the CAS7 Major Announcement: SPECIAL 3-day Pass ($10 tickets).
"Dear California Audio Show ATTENDEES,
As reported in my Facebook page, the California Audio Show has been gearing up for a major announcement. Here it is: From Monday, February 20 and onward, we will offer our $40 3-day Pass to our attendees at a 75% discount.
That's right! You can get the all-access, 3-day Pass for only $10! Supply is limited. We will end this special discount once the allotted ticket supply is exhausted. Buy one for yourself, one for your "significant other", and, at this very special price, why not buy several more as special gifts for special audiophile friends or for others that you'd like to introduce to our hobby in the very best way possible?
If you are one of our early supporters and have bought your tickets already, you have our sincere thanks! It is my pleasure to inform you that you have already been refunded the difference and everyone can attend the show for all 3 days! Any questions or issues just email me at firstname.lastname@example.org or call 510-734-4854.
Let's show the audio industry of the importance of the Bay Area. Grab your all-access 3-day Pass now and enjoy all the Sound Demos, art exhibits and Open Forums with industry personalities like Tim de Paravicini, John Curl, Gary Koh, Roger Skoff, Jack Roberts (The Dagogo Beatnik), Richard Austen (the infamous RGA on Audio Asylum) and more!
