I think of Audio-Technica as the maker of some of the best high-value cartridges out there. From the ubiquitous AT3600L, which can be had for a little more than a Big Mac meal at McDonald's, to the popular OC9 moving coil series, A-T's cartridges have long been easy-to-recommend options that deliver great sound mounted on just about any turntable.

But occasionally, Audio-Technica likes to show off its technological chops by launching a cartridge that breaks new ground. Last year, they celebrated their 60th anniversary by stunning everyone with the AT-MC2022, which uses an outrageous integrated stylus and cantilever fashioned from a single piece of lab-grown diamond. In 2016, they flexed their capabilities with the AT-ART1000, which completely reconfigured how the elements of a moving coil cartridge are arranged, with spectacular results.

Now, eight years after the AT-ART1000 was launched, A-T has introduced the AT-ART1000x, which incorporates several small but important improvements.

I spent the second three-and-a-half years of my life living with my family in Sweden. Our home was on an island just outside of Stockholm called Lidingö, which locals tell me today is like the Beverly Hills of Stockholm, a fancy place where the rich and famous live. Fifty-nine years ago, it wasn't quite so fancy; it just seemed like a cool place for a little kid from New York City to grow up.

I can't honestly say I remember many details about my life between the ages of three and a half and seven, yet apparently some of that Swedish way of thinking ended up influencing my life view, specifically, how Swedes approach consumer goods and purchasing decisions.

It started one evening when I was killing time watching YouTube videos and stumbled across a 2017 talk given by Jonathan Carr, Lyra's brilliant cartridge designer (footnote 1). After discussing his design and Lyra's manufacturing processes for about 18 minutes, Carr opens the floor to questions. Someone asks which of the many cartridge setup parameters he feels is the most important. I was floored when the first thing Carr said was that "horizontal tracking error is not very important at all." What? I couldn't believe I was hearing this from the guy who writes owner's manuals with super-specific specifications, like tracking force measured to a 100th of a gram and loading recommendations with wide but oddly specific ranges like 97.6 to 806 ohms. Did he really believe that the tonearm geometry calculations of Löfgren, Stevenson, et al, weren't such a big deal?

For decades I have painstakingly used the best tools available to perfect these settings with every cartridge I install; now a guy whose opinion I respect deeply is saying it's not very important.

Ron Sutherland makes a strong case for being crowned the king of all phono preamps, though I expect he would blush at any such suggestion. In 1979, with degrees in physics and electronic engineering (where his final project involved designing and building a digital logic–controlled preamp), he teamed up with Gayle Sanders to found electrostatic speaker company MartinLogan. ("Martin" and "Logan" are Sanders' and Sutherland's middle names, respectively.) But after a few years, he found the increasingly corporate mindset at M-L a bit stifling, so he decided to go his own way. Ron wanted to build gear he thought was cool and fun while not being directed solely by its commercial potential. He joined up with his brother to start Sutherland Engineering, creating hi-fi equipment that piqued his own interest and hopefully that of a bunch of customers.

At first, Sutherland made a wide range of components, including preamps, power amps, and DACs, but gradually he focused more and more on phono preamps. Today that's the only thing he makes...

Forty years ago, as I was starting out on my audio journey, I railed against the flashy mainstream audio gear of the day. To me less was more, and I tried to convince my friends that my small, austere British-made audio rig, including what my friends jokingly called my Lynn Swanndek turntable (after the Steelers wide receiver), really did sound much better than their big silvery Japanese stacks loaded up with shiny knobs, switches, and meters. Audio was all about the sound after all, and I wasn't interested in some dazzling visual display that had nothing to do with what I was hearing. I gravitated toward gear that wasn't flashy or fancy looking, feeling that meant that the effort and expense to create it went where it counted most, to the parts that made it sound great.

Last month, I talked a bit about some of the new gear being exhibited at AXPONA, America's big hi-fi show, held near Chicago. Well, every year, as soon as that show is over, it's time to get ready for the Big Kahuna of audio shows, High End Munich.

Admittedly, I have never attended the big shows in Shanghai, Hong Kong, or Warsaw, but it would be hard to imagine either one outdoing Munich. The Warsaw show calls itself the second biggest show in Europe, deferring, presumably, to the Munich show. Munich is so big that it even has a sideshow, HiFi Deluxe, just down the road. HiFi Deluxe caters to exhibitors who got shut out of the big show, which despite its hugeness is oversubscribed. It can all become a bit overwhelming.

The main Stereophile crew covering the Munich show—Ken Micallef and Jason Victor Serinus—did all the heavy-duty legwork, posting highlights here. I toured the halls to see what was new, collecting the best, most Spin Doctor–ish things for this report. Here's a smattering.

Spin Doctor #14: Lyra Atlas λ Lambda phono cartridge and fixing footfall problems

It has been more than a decade since 2012, when Lyra launched the original Atlas moving coil cartridge as the company's flagship, but in the intervening years, there have been a few updates. First, in 2016, Lyra introduced what they call the SL versions of the Atlas and also the Etna. These cartridges were designed to take advantage of a new crop of transimpedance phono preamps like the CH Precision P1 and the Sutherland Phono Loco, which boast exceptionally low noise levels but work best with cartridges that have very low impedance. Cutting the number of turns on each of the cartridge's two coils in half reduces the moving mass and inertia, allowing the stylus/cantilever assembly to respond more accurately to the tiny groove modulations. This results in improved tracking at the cost of a lower output level, which, thankfully, transimpedance phono preamps are well-equipped to handle.

Then in 2020, both Atlas and Etna versions were updated to new λ Lambda versions, with a redesigned suspension and damper system that Lyra says delivers enhancements in clarity and resolution.

These days, there's a hi-fi show taking place somewhere on the planet pretty much every weekend, but for me, spring is show season. First, in April, comes AXPONA, which is held near Chicago. AXPONA is the largest North American high-end audio show, making it pretty much impossible for one person to see everything during the three-day event. Even with my focus on record-playing gear, I found myself skipping some rooms, telling myself that I could catch them a month later at High End Munich. Munich is even bigger than AXPONA, so we'll have to see how that plays out.

With that in mind, here are a few things that caught my eye at AXPONA 2024.

I sometimes joke about how audio designers create products that resemble themselves, not just in how they look, but also in the design approach used, and especially the way they sound. So, we have tall, cool, pragmatic Scandinavians making gear like the lean, elegant Børresen loudspeakers, while the Italians build luscious curvy equipment endowed with natural wood and leather, like Sonus Faber speakers and Unison Research amplifiers. Continuing this blatant stereotyping, we have Acoustic Signature founder Gunther Frohnhöfer, a stout German known for creating precision-built turntables that are as solid-looking as he is.

When I visited the Acoustic Signature factory in 2023, I watched as they hewed massive slabs of aluminum into beautiful, heavyweight turntables. This approach is the opposite of the lightweight-but-rigid philosophy embraced by Rega, and while the resulting performance has different strengths, I would argue that it is at least equally valid. As with Rega, Acoustic Signature products have a purposeful simplicity, in a way that would allow a nonaudiophile to instantly recognize what their function is.

"I think both moving coil and moving magnet cartridges are terrible." That's what legendary Canadian audio designer Ed Meitner told me when I asked about the pioneering transimpedance current drive phono stage he created for his Meitner PA6 preamp some 40 years ago.

Meitner has been designing innovative hi-fi gear for the pro and consumer audio markets for more than 50 years, but for most of the last 30, he has been best known for his work with high-resolution digital audio and DSD recording. Despite this focus on digital—and despite that comment about the two leading phono cartridge technologies—deep in his heart, Ed still loves analog and has fond memories of the Kenwood optical cartridges from the 1970s, which I discussed in last month's Spin Doctor column. So when Ed read that a company in Japan called DS Audio was bringing back an improved version of the optical cartridge using modern materials, he contacted designer Tetsuaki Aoyagi to learn more.
