I used DRA Labs’ MLSSA system and a calibrated DPA 4006 microphone to measure the Marten Parker Trio Diamond Edition’s frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield and in-room responses. I measured the speaker’s impedance with Dayton Audio’s DATS V2 system. Usually, I measure loudspeakers in our backyard, weather permitting, or in our living room with the furniture pushed to the sides. This eliminates or moves back in time the reflections of the speaker’s output. However, as this loudspeaker was too heavy for me to move outside or upstairs to the living room, I performed the quasi-anechoic measurements in my basement listening room. I managed to maneuver one of the speakers, standing on its IsoPuck bases, onto a small, wheeled dolly and rolled it forward…

Archie Shepp’s Ballads A review of the Archie Shepp/Jason Moran duet album Let My People Go, in the April issue, may have startled some readers. Shepp is a tenor saxophonist known for tearing across the fiercest climes of the avant-garde (his seminal album is called Fire Music); yet at 83, he’s playing standards, spirituals, and slow blues. In fact, Shepp has been exploring such traditional terrain for several decades. So—for the debut of an occasional column on underappreciated albums, artists, genres, and labels—let’s shine some light on Archie Shepp’s ballads. The shift began in 1970, when, after his mother’s funeral, a friend of hers asked, “When are you going to record something that I can understand?” It occurred to him that few Black people were coming to his concerts. So, he started…

LOUDSPEAKER 2020 may not have been a year to celebrate, but there were some housebound highlights. For example, after I had finished with the measurements to accompany Michael Fremer’s review of the Marten Oscar Duo in the November 2020 issue,1 I set up these Swedish two-way standmounts in my own listening room. Yes, the measured performance was excellent, but I was not expecting how much I would enjoy the sound of the Oscar Duos. At $6995/pair, this is not an inexpensive speaker, but it rivaled the stereo imaging produced by my reference KEF LS50, played louder than the diminutive KEF without strain, and offered another octave of low frequencies. As MF concluded in his review: “Designer Leif Olofsson has threaded the needle, producing a small speaker that can produce prodigious bass…

The NAD C 298 can be operated as a conventional stereo amplifier or as a bridged-mono amplifier. (In mono mode, the signal is fed to the left input and the output taken from the left channel’s positive binding post and the right channel’s negative binding post.) As Kal Rubinson auditioned the NAD both in stereo mode and as a pair of monoblocks, I performed a complete set of measurements in both modes. The C 298 has an output stage operating in class-D, so I inserted an Audio Precision auxiliary AUX-0025 passive low-pass filter between the test load and my Audio Precision SYS2722 system (see the January 2008 “As We See It 1”). This filter eliminates RF noise that could drive the SYS2722’s input circuitry into slew-rate limiting, and I used…

In its sixth year, International Anthem seriously stepped up production. 2020 saw the Chicago label releasing a fast succession of rewarding albums, including a standout disc by Tortoise guitarist Jeff Parker and adventurous jazz by Rob Mazurek and the collective Irreversible Entanglements. Within that flurry of activity, the small operation drew a fine line through a new era of jazz spiritual. Not a narrow line, but a fine one, a bold and exceptional line. Harp/bass duo Dezron Douglas and Brandee Younger’s Force Majeure included arrangements of tunes by Alice and John Coltrane and the Stylistics; drummer Makaya Mc- Craven continued his beat-heavy Universal Beings groove with an album that included contributions from Parker and Younger; and clarinetist/singer/songwriter Angel Bat Dawid followed her stunning 2019 debut with a live album and…

POWER AMPLIFIER Once upon a time, in the early days of class-D amplification, the very notion that the ELAC (ELectroA Coustic) Alchemy DPA-2 Stereo/Mono Power Amplifier ($1495 each) uses a class-D output stage would cause some readers to turn the page.1 But as class-D amplifiers established their pedigree as bona fide hi-fi components, audiophiles have begun to embrace the notion of a lightweight, cool-running amplifier that will not dramatically increase the electric bill and that, when properly executed, can be quite musical. Others, though, may still balk at the suggestion that this skinny, 14lb, class-D device from the Americas division of ELAC Germany—auditioned here in bridged monoblock configuration—can get listeners close to the heart of the music. Perhaps learning that the DPA-2 was designed by Peter Madnick, who also oversaw the design…
