there's the los angeles orange county audiophile society www.laocaudiosociety.com i'm not a member but have heard that they're a pretty big club.
The web address for the Los Angeles/Orange County club is:
Don't dismiss it just because you live in the valley. The club travels to different venues all over LA and OC. The last event was at Brooks Berdan's place out in Monrovia, which isn't that far from Glendale.
Take a look at their website and you will see that they are worth looking into.
