Is there a Northern and Southern California Sound

Hi everyone,
I've been slowly making the rounds of LA stereo shops. Before this I was in the San Francisco bay area.

Ages ago, speakers were divided into two camps: East Coast and West Coast sound.

East coast was Audio Research, Boston Acoustics, KLH, etc. West coast was Altec, JBL.

After listening and thinking about it I am wondering if there is a preference for sound quality in northern Caslifornia vs. Southern california?

I got to hear systems in the north at Magico, Music Lovers and Audio Visions. Here in the South I've heard a couple of places, and I found the sound harder and brighter.

Of course, this is a small sample, and all electronics were different, but I'm wondering, has anyone else heard the same?
