Stereo Design in San Diego. My favorite dealer. Look them up on the internet. I go there when visiting my Friend living in San Diego as often as I can. I have been auditioning equipment or purchasing outright from them for decades. The staff is very good and helpful and their used equipment room has excellent equipment. They never try to sell you anything. Just set up the equipment or let you use one of their many equipped rooms and you are on your own. I am often (when interested in purchasing) allowed to "borrow" equipment for in-home auditions for a week or so. As long as the dealer has your credit card information, they should have no problem doing this. Also, I live in Los Angeles. That shows the great relationship that they develop with customers.
Most of my equipment was purchased from there.
