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.

John Hébert's experiences unearthing precious oddities have served him well as an adult musician, particularly when extracting deep bass sounds as one of New York City's most in-demand jazz bassists. From his 1990s-era Romanian and Hungarian upright basses and exotic stereo gear and LPs to the Baldwin grand piano that adorns the living room of his Jersey City, New Jersey home, Hébert is a perfect example of audiophile as musician.

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.
