Art's Blog: California Audio Society 2019 Show

The 2019 California Audio Show was held between July 26th-28th at the Hilton Oakland Airport.  Dagogo hosted the show for its 9th year serving as the main audiophile show for the SF Bay Area and Silicon Valley.  Special thanks go to Constantine Soo and his great crew of helpers and editors.  Acoustic Sciences was fortunate to have its booth positioned near one of the main entrances where we acted as greeters and helped the attendees remember the importance of room acoustics in pursuit of high fidelity audio playback.

Complete reporting of the event, by the organizers, can be found on the Dagogo site.

Stay tuned for detailed discussion of each of the rooms in which TubeTraps were included in the demonstration systems.  In the meantime, please check out an early report of the show written by Dagogo editor David Blumenstein.  The entire article can be found here.  Check back for more installments!

“The 2019 California Audio Show, “CAS9” as it unfolded, as it was and is destined to be in its past, present and future incarnations. CAS shall always be an intimate affair, not by design, not as artifice, but by its very core principles. It truly is a family affair. All one need do is look to the extent of involvement and dedication of Constantine and Vivian Soo and their extended family, actual relatives and Dagogo staffers, of which I am one. We all pitch in on the organization, planning and execution of CAS and that will be no different in this coming year as CAS celebrates its 10th anniversary.

Holger Adler of Voxativ Acoustic Technologies and an exhibitor this year put it best:

“My personal impression of the show was how Constantine Soo and his partners: Byron Baba, David Blumenstein and Doug Schroeder created a feeling that is simply the meeting of old and good friends who like each other. I enjoyed my stay very much and I will be back next year with Voxativ Acoustic Technologies.”

This is what the crew strives for on behalf of CAS, its attendees and its exhibitors. The intention is that nobody on either side of the equation feels any pressure, and that there can be open discussion between all parties without feeling the need to rush off to the next exhibit.

A noticeable first this year was quite possibly the best sounding speaker/panel room ever at any Hi-Fi show on record. It’s not so much the quality of the Behringer gear, but the sheer number of ASC TubeTraps in the room…”  … the article continues here!

This was actually an impromptu discussion, it is amazing to see him discuss acoustics in real time.
