Magico M2 loudspeaker Measurements

Sidebar 3: Measurements

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the Magico M2's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield and in-room responses. The 165lb loudspeaker was too bulky to move outside for testing or to lift onto my computer-controlled turntable. I therefore had to do the quasi-anechoic measurements in my listening room, where the proximity of room boundaries led to more aggressive windowing of the time-domain data than usual, which in turn reduced the graphs' resolution in the midrange.

Four Interviews with John Atkinson

Occasional Stereophile contributor Steve Guttenberg publishes a YouTube channel about audio that has achieved an impressive reach. As Steve told me in a conversation I had with him last December, 22% of his 98,000 subscribers (at the time we talked) are under 34 years old, and, to judge from the comments, most of them don't read Stereophile!!!! "It would nice to introduce you to them!" said Steve, and proposed he interview me and post the video to his channel when it hit the magic 100k number, which it did on January 9.

Steve visited my place in Brooklyn just before the New Year, and we…

Listening #206: Shindo Cortese amplifier

Only recently did I learn that successive generations of the Chevrolet Corvette are referred to by the cognoscenti with two-character alpha-numeric identifiers: C1, C2, C3, and so on. I learned this while reading about the most recent version—C8, known to non-cognoscenti as the 2020 Corvette—which happens to be the first version since C2 that impresses me. (I say that as one who used to work for the owner of a C3, a then-middle-aged male who actually boasted, while under the influence, that he and two of his C3-owning friends drove them solely because their juvenile styling attracted…

Listening #206: Shindo Cortese amplifier Page 2

But note also, irrespective of the loudspeaker in use: In every listening session I've enjoyed so far, the Cortese has taken at least an hour to warm up—and even then its sound continues to improve over at least another hour. I don't recall another Shindo that has taken as long to perform at its best, and that leads me to guess that this sample still has a while to go before it is fully broken in. Which is kind of fun, really.

And note that other Shindo setup tricks to which I've alluded in the past hold true here. In particular, also like all Shindo amps of my acquaintance, it seems…

Dan D'Agostino Master Audio Systems Momentum HD line preamplifier

I thought I knew what a preamp could do. But when the Dan D'Agostino Master Audio Systems Momentum HD preamplifier ($40,000) arrived for review, all my expectations flew out the window.

The two-piece Momentum HD preamp wasn't exactly a stranger. I'd heard it in two of the finest sounding systems I have ever encountered, at a March 2019 event at Seattle's Definitive Audio and, a month later, at Chicago's 2019 AXPONA. Both systems included Wilson Audio Specialties' Alexx loudspeakers and Subsonic subs; D'Agostino Relentless monoblock amplifiers paired with the Momentum HD preamp (and other…

Dan D'Agostino Master Audio Systems Momentum HD line preamplifier Page 2

Switching between all those pieces of equipment while keeping power cables and interconnects separate, ensuring optimal setup consistency, and taking coherent notes is not for the faint of heart. A touch of madness helps. Some may be tempted to resort to mood stabilizers or out-of-body escape when they realize that, because the Momentum HD preamp lacks a numeric volume display, it's virtually impossible to match volume levels by sight. There's a reason for the manual's caution: "The dynamic capability of the new Momentum HD Preamplifier is beyond what is normally experienced with other…
