Good stores in LA

Dr.Jack left the Encino store about a year ago. It is currently being run by his partner. I don't know If he is still Involved with the operation of the business.

Sound Factor was called Sound Circuit in the 70's.....I bought my first reciever there, a Sansui 771 at the Ventura Blvd store in '75.

Gene Rubin is great If you are Into Naim electronics and Harbeth speakers.

Down here is SanDiego, which until reading the above posts, I'd have thought of as the end up the world, has a couple of places of note:
1, just up the street in Carlsbad has Mac, CA, PassLabs, Paradigm speakers and a bunch of other goodies. I bought a PSAudio Soloist outlet there last year.
Down South is another operation with no less than 7 or 8 demo rooms. Wadia, Krell....electronics and speakers.....B&W, Rotel, Naim, Rega, Magnepan, and many more. Good used selection and great staff.
There is a mid-fi place or 2 with NAD offerings, include the 'M' stuff. More boutique AV/HT places than you can shake a stick at finish it off.
Not a lot, but overall pretty nice.
