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. Outside the US, it will continue to sell through authorized dealers.

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.

Godzilla and I are precisely the same age: We were both born in 1954, Godzilla as an expression of the postwar fears of a nation uniquely aware of the horrors of nuclear armaments, I as an expression of the postwar comfort felt by an American veteran fresh from foreign wars. We both dislike being awakened from our slumber, and we're both unusually handsome.

Accustic Arts of Lauffen, Germany, was founded in 1997 by Fritz Schunk, who sold the company to Hans-Joachim "Jochen" Voss in 2016. Voss's professional background had more to do with sweet spreads than sweet sounds—he spent 20 years doing sales and marketing, including with the Ferrero Group, which produces Nutella—but he happened to own some Accustic Arts components, and as a music-loving consumer with a special fondness for rock, had been in touch with Schunk for many years before the company went up for sale.

It is said that while any competent engineer can design a superb loudspeaker if allowed an unlimited bill of materials, the true test is being able to produce a great-sounding, budget-priced speaker out of parts that cost a mere handful of dollars. With PSB's Alpha series of bookshelf speakers, Canadian engineer Paul Barton has illustrated this truism many times over the years.

Class-D audio amplifiers: What's the argument for them? Class-A audio amplifiers: What's the argument against them? Class-AB amplifiers: Why does everybody make them? Each of these amplifier output architectures has strengths and weaknesses. Each will interface more or less successfully with a given loudspeaker in a given room. Each has a distinctive sonic signature. Consequently, as knowledgeable audiophiles with a laundry list of system-building goals, we are required to choose the amplifier type that best suits our speakers, our room, and our individual musical-aesthetic predilections.
