Have you joined up with the SFAS (San Francisco Audiophile Society)? The name is somewhat of a misnomer as I haven't seen them have even one event in San Francisco, but I think many of their get-togethers are in South Bay. I live in SF and don't drive so I don't go to those.
San Jose CA
Is there anyone in the San Jose area who would be interested in forming a new audio club? I live in Willow Glen. .
