Interviews

Twenty-three years ago, in 1993, Charles Hansen cofounded Ayre Acoustics, Inc., in Boulder, Colorado. On Ayre's website, Hansen is named as Research Director for Ayre, and it seems an apt description. Along with experimenting in and developing audio-electronics hardware and software, Hansen has strongly hewn to certain design principles, among them fully balanced operation, an absence of loop negative feedback, and solid-state circuitry. Ayre's current flagship preamplifiers and amplifiers, the twentieth-anniversary R Series, have received reviews and accolades, while at the other end of the budget spectrum, Hansen's design work was a key element of Neil Young's widely publicized and crowdfunded PonoPlayer project.

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.

Label heads—those at the very highest positions of power at music companies. To anyone who's spent time near the record business, they're a mythical breed. Like gnomes. Or dragons. Often, it's their vision that spells success or failure for the label they run. And what they say goes. Over the years, many a legendary creature has assumed the title: Goddard Lieberson, Clive Davis, Mo Ostin, to name just a few of those who have survived and prospered. The list of those who did not is at least twice as long.

To accompany my review of the Dan D'Agostino Master Audio Systems Progression monoblock amplifier elsewhere in this issue, I talked to Dan D'Agostino about the amplifier's design. I started by asking him what were some of the major differences between the Momentum and the Progression monoblocks?

Dan D'Agostino: I took the best parts of the Momentum's more sophisticated and complex circuitry and put them in the Progression, without using the same high parts count. Each stage of the Momentum's gain amplifier is separate, with input stage and driver stages on separate rails. All of the Momentum's devices are designed for maximum performance in a small package, which requires a lot more of them, and a significantly bigger input card than the Progression's. These differences create subtleties, because I'm able to run much higher current in the Momentum's front end.

Dave Alvin is a fighter. In the 1980s, when Dave and his older brother, Phil Alvin, shared studio and stage as co-founders of Los Angeles punkabilly band The Blasters, they frequently fought each other. They also fought musically, tussling over every note as the four-man band wrangled many great tunes. In that respect, their working relationship may have been similar to the sibling push-pull output of Ray and Dave Davies in the Kinks and Liam and Noel Gallagher in Oasis. Consider "American Music," "Marie Marie," and "Border Radio," all from the band's 1981 sophomore album The Blasters, as examples of how internal conflict can lead to successful collaboration.

David Chesky, whose company has been making superior recordings for nearly 20 years now, isn't from the engineering side of the business. He's talent—a pianist who sometimes performs on his label, a composer of classical and jazz selections integral to its catalog, and an arranger as well.

Wes Phillips: How did you come to design the WATT—and the Puppy?
