Is there an audio shop anywhere in SoCal where you can audition cans? I can't find one that does. So many people mention their local dealer. I still haven't found one here. Any help out there?

First post for a lurker. I'm looking at closed headphones because I share a meditation room with my wife and she doesn't want to hear anything i'm listening to (she may like it, but it's her room). I would have loved to purchase Grado's but not a possibility at this time. I'm looking for cans...
