Armando Anthony "Chick" Corea belongs to that elite cadre of pianists that includes Herbie Hancock, Keith Jarrett, and Mccoy Tyner, pioneers who reshaped the jazz or- der starting in the early 1960s and continued to make strides into the present day.

The now-78-year-old Corea's attainments are many: composer of the standards "la fiesta," "Spain," "500 Miles High," "Matrix," and "Windows"; winner of 22 Grammy Awards (and 64 nods); founder of at least six colossal improvising units (Return to Forever I and II, Circle, the Three Quartets quartet, the Chick Corea Elektric Band, the Vigil Quintet); popularizer of early monophonic synthesizers, and recipient, in 2006, of an NEA Jazz Masters award.

In a late-August newsletter, PS Audio announced a major change in how it does business. In the United States, its home market, the company stopped selling its products through dealers and opted for a direct, online-only sales model.

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.
