What I failed to make absolutely clear in my April column is that I really, truly, thoroughly enjoyed all three USB DACheadphone amps that I auditioned: the Audioengine D3 ($189), the AudioQuest DragonFly v1.2 ($149), and the Cambridge Audio DacMagic XS ($199). Each offered a slightly different perspective on the music, but none could be accused of closing lanes on the George Washington Bridge, dumping several feet of snow on top of our car, or doing anything especially wrong.
Thomas Alva Edison may have had a fully equipped laboratory, with a team of assistants slaving every day over ideas to be adopted when ripe as those of the great inventor, but the image of American ingenuity which rings true to me is of the lone tinkerer, working alone and mixing a generous dose of good ol' Yankee know-how with the sweat of his browa lot of it. These days, with the faithful PC and a hardworking CAD program at his side to do the math, the lone tinkerer seems to be thicker on the ground than ever, to judge by the humongous numbers of small companies selling high-end hi-fi components as revealed in Stereophile's readership survey (see p.5). Whether these loners will ever rise above their origins depends, among many other things, on their ideas being truly worthwhile.
One reason Stereophile publishes a FollowUp is when the original review leaves an issue unresolved or where further thoughts would be useful. Such was the case with the magazine's March 2022 issue, which had followup reviews on the iFi ZEN CAN headphone amplifier and ZEN DAC Signature V2 D/A processor ($599/pair). the Pro-Ject Phono Box RS2 phono preamplifier ($1999), and the Canton Reference 7K loudspeaker ($6995/pair).
Michael Fremer wrote about the Paradox phono preamplifier in the March 2022 Analog Corner, Jim Austin reviewed the CH Precision D1.5 CD/SACD player/transport in March 2022, and Herb Reichert included the EJ Jordan Marlow standmount speaker in his April 2022 Gramophone Dreams column. All three products get further coverage in Stereophile's May 2022 issue.
Few people in the audio business would deny that John Curl is an audio design genius—arguably the greatest one of our generation. He designed and built the electronics for Mobile Fidelity's SuperMaster and David Wilson's (of Wilson Audio) UltraMaster tape recorders, two of the three best analog recorders in the world. (The other is Keith Johnson's home-brew unit.) He designed the JC-1 head amp and JC-2 preamplifier sold under the Mark Levinson name some years ago. He designed head amps for SOTA, Michaelson & Austin (TVA), and has done consulting work for more high-end companies than you can shake a stick at.
This massive, two-box beauty from Denmark costs $60,000, and I wish I could tell you it wasn't really better in most ways than the already outlandishly priced and sonically superb Boulder 2008. I can't.
Like the $29,000 Boulder 2008 phono preamplifier, the new Whest PhonoStage.20 with its MsU.20 power supply costs as much as a car. Fortunately for you, that car happens to be my first new Saab, which cost exactly $2737 back in 1972. The solid-state Whest costs $2595, so it's a few hundred dollars cheaper. But at only a tenth the cost, it comes closer to the Boulder 2008's performance than it has any right to. That it's good enough to be mentioned in the same paragraph should tell you something about how good I think it is. Nor did it come to me hyped by the manufacturer—it took me by surprise from the minute I first heard it. I began my listening right away, before reading anything about the circuit design.
Maybe you've seen the widely circulated New Yorker cartoon: Two guys stand in front of a nicely drawn, tubed audio system, under which are shelves full of LPs. One guy says, "The two things that really drew me to vinyl were the expense and the inconvenience."
If you can't laugh at that, you've lost your sense of humoreven acknowledging that, oddly, convenience is the raison d'etre of some recent phono preamplifiersincluding Dan D'Agostino Audio's Momentum and the CH Precision P1, both of which offer multiple, switchable, configurable inputs saved in memory. Today's well-heeled vinyl enthusiast might have two or more tonearms mounted on a single turntableor even two turntables, each with two arms. Zesto Audio's new Andros Téssera tubed phono preamplifier takes aim at that market segment.
