Audio Vision SF, one of San Francisco’s two major high-end dealerships, celebrated its 20th anniversary on September 27–29 with a three-day celebration in two locations.

Descriptions of the sounds of products from Sutherland Engineering nearly always include "refined." While that word is certainly justified, it would be more apt to use it as a verb: Ron Sutherland spends more time than any audio designer I've known studying and fine-tuning and refining every detail of his work. I have the impression he knows those products so well that when he decides to design a less expensive version of his newest and best models, he knows exactly what to do.
