Moving to SoCal?
Being you're an audio enthusiast and here, already says somethings not right,but MOVING to SoCal? Are you retired with a fat wallet? Weather is great, way too many people, horrible traffic anywhere and what you read about the cost of living is pretty much correct.
Otherwise, paradise. Can't imagine living anywhere else, and I know there are beautiful areas in plenty of other states.There's a reason people from all over the globe keep coming to this insane state.
Did you find one of the few remaining, undiscovered pockets of SoCal, that is sane?
Disclosure-I'm a SoCal native.
All the recommended shops are good. Some, better than others. Upscale is strong with Focal,Tannoy and of course Prima Luna, since the owner is the distributor.
