In early 2020 I had the good fortune to review EMM Labs’ DV2 DAC-preamplifier ($30,000), and despite my efforts, I struggled to find fault with it. Consequently, the DV2’s fit, finish, and performance remain the benchmark against which I compare all components of its ilk, including the subject of this review, Linn’s next-generation Klimax DSM ($39,000 when configured as DSM AV, see below, all prices USD). Unlike the DV2, a digital-only preamplifier equipped with a SOTA volume control and a world-class DAC, Linn’s Klimax DSM offers features beyond the scope of the DV2, including analog inputs, two control apps, onboard lossless streaming, and onboard room-correction software. Linn’s reimagined Klimax DSM is by far the most complex, feature-laden audio component I’ve ever reviewed.

Reviewers' Choice Swordsmiths, samurai, and a little magic

You may be surprised to hear that moving-coil cartridges can trace their origins all the way back to 1946, when Ortofon developed a prototype. Since its commercial launch in 1948, the moving coil (MC) has become firmly established as the ne plus ultra for vinyl replay. The MC market is well served, with major manufacturers like Ortofon and Audio-Technica offering a wide variety of designs ranging in price from $200 to over $1000 (all prices in USD). Despite the scale of such firms and their impressive performance engineering capabilities, there’s another sector of the market that remains primarily the domain of smaller, niche operators.

Dynaudio has been designing and building loudspeakers for more than 40 years. In that time, the company has contributed some fairly significant products, like the Consequence loudspeaker back in 1983, the Evidence Master in 1989, the Confidence C1 Signature in 2011, and of course, the Special Forty in 2017.

Reviewers' Choice The most anticipated SoundStage! Ultra review of 2022 did not get off to the smoothest of starts. Full disclosure: the missteps had absolutely nothing to do with Gryphon Audio Designs or SoundStage!

Nonetheless . . .

Engineer and high-fidelity enthusiast Jacques Mahul founded Focal-JMlab in 1979. He began making speaker drivers at a family-owned engineering company in Saint-Etienne, France. Not long after, Mahul built his first speaker, the DB13, a standmounted design released in 1982 under the JMlab brand name. The DB13 was one of the first speakers to utilize a double voice-coil speaker driver, which enabled it to play as loudly as many floorstanding models of the time.

Audiovector, based in Copenhagen, Denmark, has been producing high-end loudspeakers for over four decades. And, as you can imagine, a company that has been producing speakers since 1979 must have an impressive product selection. I chose one of their newest models to review, the R 6 Avantgarde.

Deep in the Gloucestershire countryside, nestled in a pretty country lane between wild hedgerows, lies the headquarters of perhaps the world’s most respected manufacturer of professional loudspeakers. Since 1974, ATC—the Acoustic Transducer Company—has designed, engineered, and built professional monitor systems for a client list that seemingly includes most of the leading recording or mastering studios on Earth. ATC speakers hang in the Sydney Opera House, the Royal Festival Hall, and Ronnie Scott’s Jazz Club. ATC speakers were used by Doug Sax at The Mastering Lab while he was cutting many of his vinyl masterpieces. The company’s client list reads like an A–Z of the world’s most beloved artists, including Enya, Kate Bush, Bruce Springsteen, Mark Knopfler, and Pink Floyd. In short, if you want to hear Pink Floyd the way that David Gilmour does, you’d better use ATC speakers.

“This Denafrips DAC is very good. And really well built. Like, really well built.” It was Tuesday, and SoundStage! publisher Doug Schneider was telling me about the company’s flagship Terminator-Plus DAC over the phone while, as so often happens, I was trying to attend to my corporate day job. “Uh-huh,” I murmured, kinda, sorta listening. I knew Denafrips as the manufacturer of some relatively affordable digital gear that had made a splash amongst YouTube reviewers in recent times, and being a reviewer myself here at SoundStage! Ultra, I was completely unprepared for what Doug said next. “What if you reviewed their Venus II for SoundStage! Ultra?” My attention was immediately wrenched from my work email, and I bemusedly blurted, “Uh, what? Why?” I knew the Terminator-Plus—which like all Denafrips products is sold in Singapore dollars (SGD)—retailed for less than $6500 in the United States based on then-current conversion rates, and that the Venus II retailed for less than $3000. No matter how good the Venus II was, in my head, its pricing automatically ruled it out as an Ultra product. But Doug, my stubborn, combustible friend from the Great White North, encouraged me to be open-minded. I’m glad I was, because the times, they are a-changin’.

Alta Audio is based in Huntington, New York, and manufactures a growing line of loudspeakers, all of them designed by company president Michael Levy. For my review, I chose a smallish floorstander, the Alec, for several initial reasons. First, the Alec is a two-way design that weighs under 100 pounds. My current reference loudspeaker, the Sonus Faber Maxima Amator, is similar in size and form factor; like the Alec, it’s also a slim two-driver, two-way floorstander with an ambitious design brief. Having several months of listening to the SF under my belt, I knew I wanted to sample another speaker model that would compete directly with the svelte Italian. The Alta Audio Alec fit the bill perfectly.

So, you’ve assembled this great high-end system—components, speakers, cabling, isolation devices, various tweaks, and so on—and you’re experiencing what you believe is the highest fidelity your system is capable of. But have you considered power conditioning? The subject is not nearly as controversial as it once was. Most major audio magazines, this publication included, have extolled the virtues of cleaning up the power that runs from the wall to your stereo.
