darTZeel NHB-108 model two power amplifier


Like the proverbial pot of gold, darTZeel's golden equipment beckons. That, at least, is how it felt in January 2010, when John Atkinson and I ended our coverage of T.H.E. Show Las Vegas in the room shared by darTZeel, Evolution Acoustics, and Playback Designs. Listening to darTZeel's discontinued NHB-458 monoblocks (footnote 1) and NHB-18NS reference preamplifier (now updated), I was transfixed by the fullness of the system's midrange and overall beauty of the sound. "It was as though the system was opening its heart and welcoming us in," I wrote. "That's how warm and nurturing the sound was."

CH Precision D1.5 SACD/CD player/transport

There's a school of thought that maintains that among all hi-fi components, the D/A converter is easiest to perfect or come close to perfecting. Just make sure that every sample is converted accurately, that there's little rolloff in the audioband, that aliased images are suppressed almost completely, and that background noise is extremely low, and you have a top-quality D/A processor. Use of a high-quality DAC chip is assumed.

Estelon Forza loudspeaker

You've got your 2001: A Space Odyssey speaker, which of course is a tall, black, featureless monolith. Then there's your wooden "Who's buried inside?" speaker, your "R-I-C-O-L-A" speaker, your enema bag or double-inverted enema bag speaker, your menacing hooded-Klansman speaker, your "looks like a robot, praying mantis, or Transformer" speaker (mine), and your "Does it leave a slime trail?" speaker (looks like a snail). You've got your "Is that a room divider?" speaker, your "looks like you stepped on a duck's head" speaker, and your "whipped cream dollop suspended in time" speaker.

Dan D'Agostino Master Audio Systems Progression M550 monoblock power amplifier

We audiophiles so frequently get caught up in the pursuit of perfection that some have attempted to rebrand high-end audio as "perfectionist audio." But is it even possible for a single piece of audio gear, let alone an entire audio system, to attain perfection when there's no common agreement as to what "perfection" means? It's easier to cue up a Nirvana track than to find the way to audio nirvana.

Analog Corner #314: OMA K3 turntable & Schröder tonearm

If you're going to spend a year-plus in COVID lockdown, it doesn't hurt to have a million dollars' worth of turntables keeping you company, right? That's been my good fortune. Sounds like a roomful, but it's only three: the SAT XD1, the TechDAS Air Force Zero, and the OMA K3 ($360,000, footnote 1).


You'll find this issue's cover girl either strikingly beautiful or homely. Visitor reactions fall strongly into one of those two camps, with nothing in between. I love the looks. Whatever your opinion, the K3's visual distinctiveness cannot be denied. The innards are equally unique.

TechDAS Air Force Zero turntable

The Air Force Zero turntable is very large for a turntable, but it is not as large as a house. At $450,000 for the base model, it does, however, cost as much as many houses and more than many others (footnote 1).


This observation will set off howling among some audio enthusiasts of a sort that never happens in the wine world, for instance, where well-heeled oenophiles routinely spend large sums for a short-lived thrill.

Audiovector R 8 Arreté loudspeaker

Many loudspeaker designers are minimalists at heart. They embrace a design aesthetic that says that simpler is better. Based on the evidence of the company's R 8 Arreté, Ole Klifoth, of Danish loudspeaker maker Audiovector, is not one of those designers.


On its website, in the Specifications section for its "R"-model loudspeakers (footnote 1), Audiovector offers a long checklist of technologies, many of them optional, some of them, called "Concepts," assigned snappy names and acronyms: IUC for Individual Upgrade Concept; LCC for Low Compression Concept; SEC for Soundstage Enhancement Concept; NES for No Energy Storage; FGC for Freedom Grounding Concept; and NCS for Natural Crystal Structure.

Esoteric Grandioso C1X line preamplifier


Even as I was admiring some of the handsomest audio gear I'd ever set eyes on, my thoughts kept returning to equipment of a very different sort.


Flash back maybe 40 years to my one-bedroom apartment on Elgin Park in San Francisco during the period when I was whistling for my supper and performing Puccini's "O mio babbino caro" in the Emmy-nominated Peanuts cartoon, "She's a Good Skate, Charlie Brown." Cue the constant din of an elevated four-lane freeway, since demolished as a blight on humankind, which I tried to pretend was the sound of water in the accompaniment to one of Schubert's many "water and fish" songs.

Wilson Audio Specialties Chronosonic XVX loudspeaker

Brand-fan excitement ran high among consumers and reviewers alike when Wilson Audio Specialties announced that it would roll out a nonfunctioning prototype of the Chronosonic XVX at the 2019 Rocky Mountain Audio Fest (RMAF). The Chronosonic XVX was rumored to be a replacement for the $210,000/pair Alexandria XLF, offering performance similar to that of the $850,000 WAMM Master Chronosonic system (including two Master Subsonics and a controller) at a less breathtaking price. (You won't catch me writing "affordable" here.) The static unveiling at RMAF intensified anticipation.
