Cecile McLorin Salvant, Dreams and Daggers

It was almost exactly a year ago that I first heard Cecile McLorin Salvant at the Village Vanguard. I came home and wrote a blog for this space, wondering how I could have missed her ascent (she'd already won a Grammy and other prizes) and deeming her the best jazz singer around, standing among the greats of all time. I went back to see her, dragging along my wife and two friends, the following Sunday—the late set, the final set of his week-long stint—and she was better still . . .

Dan D'Agostino Progression Mono monoblock power amplifier

For as long as I've known about high-end audio, I've put Dan D'Agostino, co-founder of Krell, on the same pedestal reserved for the likes of Frank McIntosh, Saul Marantz, Avery Fisher, H.H. Scott, and Sidney Harman. The reason is simple: Dan's the man whose achievements at Krell led me from the harsh sound of my first high-end amp into another dimension, one of truly musical sound reproduction.

Dan D'Agostino's Progress to Progression

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.

Linear Tube Audio ZOTL40 Mk.II power amplifier

I have always been fascinated by audio power amplifiers. I even tried building about a hundred of them. My best friend in high school, Bill Brier, taught me the basics of soldering, wire management, and reading schematics. He loaned me his Dynaco Stereo 70, and gave me a hot-running, 20W, class-A transistor amp that he'd built on his mother's kitchen table. Bill took me to concerts, and taught me about classical and jazz music. He had perfect pitch, tuned pianos for money, played every instrument in the orchestra, and had memorized the complete keyboard works of J.S. Bach before he turned 16. And this stuff was all on the side—mainly, we built drag race cars together.

PS Audio DirectStream Memory Player universal transport

The first time I heard a CD player in my own system was in 1983, the first year of the format's introduction in the West. CD players were generally hard to come by, but I had a friend who worked for Sony, and he came over with his new toy: Sony's next-to-top-of-the-line CD player. (I think it was a CDP-501.) We connected it to my system—at the time, Quad ESLs driven by a Luxman tube amplifier, with a Linn turntable—and listened to some Sony demo CDs.

KEF Reference 5 loudspeaker

Of all the speakers I have most enjoyed in recent years, two were from British manufacturer KEF: the LS50 Anniversary Model ($1500/pair), which I reviewed in December 2012; and the Blade Two ($25,000/pair), which I reviewed in June 2015. Though these two speakers lie at opposite ends of the price scale, they have in common KEF's unique Uni-Q drive-unit, in which the tweeter is mounted on the front of the midrange unit's pole piece, so that the lower-frequency cone acts as a waveguide for the higher-frequency output.
