LATEST ADDITIONS

I am a big believer in supporting events promoted by specialty audio retailers. They reinforce the idea that audiophiles and manufacturers—even reviewers—are parts of a vibrant community that believes that listening to music with the highest possible quality is one of the more important things in life. The "Music Matters" evenings arranged by Audio Advice in North Carolina, Definitive Audio in Seattle, and Listen Up in Colorado exemplify that idea, and it was in April 2015, at Listen Up's Denver store, that I used a pair of PSB's new Imagine T3 tower speakers to play the audience some of my own recordings. The T3 superficially resembles PSB's Synchrony One, a speaker I very favorably reviewed in April 2008, and I was equally impressed by the new flagship—impressed enough to request a pair for review.

Simaudio saw disc-based digital audio in its rear-view mirror at least as far back as 2011, when it introduced the Moon Evolution 650D and 750D—two iterations of what it called a "digital-to-analog converter CD transport." These were actually multiple-input CD players, but Simaudio was evidently so eager to distance itself from the spinning disc that it went with a product category that, in spite of its cumbersome, run-on name, drew a clean line between the disc-reading and signal-processing functions—while bestowing upon the former second-class citizenship.

Two of the great jazz pianists on the scene have just released two of their greatest trio albums: Fred Hersch, Sunday Night at the Vanguard (Palmetto); and Brad Mehldau, Blues and Ballads (Nonesuch).

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.

New York, NY—News Bar Cafe, Union Square. It's 11am. Low jazz can be heard playing on the overhead speakers, along with background chatter and the occasional ambulance. Caffeinated beverages and breakfast sandwiches are present. I take a tentative sip of cappuccino, reach under the table for my trusty Zoom H5. Across from me sits jazz pianist and composer Fred Hersch. A man who has meant many things to me in my lifetime—a musical role model, a source of inspiration, a friend, a set of frequently played digital music files... I sit anxiously—is it the awe or the beverage? I think to myself: he's now entering the realm of debatable audiophile and breakfast co-conspirator. Cappuccino sip. Let us begin.

In New York City or more specially Corona, Queens, July is the month when thoughts turn to the legacy of one Louis Armstrong. Last weekend, I made the pilgrimage with my patient wife to the Pops home in Corona, to view what is now the Louis Armstrong House Museum.

The DQ-12 is the latest loudspeaker from Dahlquist employing their "Phased Array" technology, first used in 1973. The company was formed that year by Jon Dahlquist and Saul Marantz to produce the DQ-10, a loudspeaker that enjoyed a long and successful life. When I sold hi-fi in a retail store in the late 1970s—we stocked Dahlquist speakers—the DQ-10 was among the more prominent audiophile speakers, prized for its imaging abilities.

In 1976, Carl Marchisotto joined the company, designing support products for the DQ-10 including a subwoofer, variable low-pass filter, and a passive crossover. Jon Dahlquist is no longer actively involved with the company; Carl has now assumed the engineering responsibilities at Dahlquist and is the designer of the latest group of Phased Array loudspeakers (footnote 1). This new line, introduced at the Winter 1990 CES in Las Vegas, encompasses three models: the $850/pair DQ-8, the DQ-12 reviewed here, and the $2000/pair flagship, the DQ-20i.
