Over the last 50 years, I must have installed well over 1000 phono cartridges, but I still remember the very first one: a Goldring G850 I put into the family Garrard Autoslim turntable when I was 11 years old. In 1973, the G850 was the least expensive moving magnet cartridge Goldring made. The change from the flipover-stylus ceramic cartridge that came with the Garrard wasn't an attempt to satisfy a youthful audiophile itch but, rather, a result of my first encounter with a system compatibility problem.

A few months earlier, I had convinced my nonaudiophile dad to upgrade the family stereo. We went from our ancient Monacor SMX-50 tube receiver to a pretty weird but less ancient Sony all-in-one cassette system called the TC-133CS. I failed to understand that the new Sony's magnetic phono input was incompatible with our old ceramic cartridge. Once I figured that out, I tried to convince my dad that what we really needed was a Shure M75ED. After all, that cartridge came from the same company that made the legendary V-15 Type III, widely regarded as the best cartridge in the world at the time. My dad, however, had different plans. Guided by his home-product purchasing bible, Consumer Reports, he decided we should go instead with the less-costly Goldring.

In prior screeds, I have discussed the category of turntable designers I like to call deep thinkers, who twist their brains to come up with fresh thinking about how to approach the task of playing a vinyl record. If there is a poster boy for deep thinkers, it's got to be Simon Brown.

Brown is based on the South Island of New Zealand. I'm thinking that being in such a far-flung part of the world must have given his head plenty of space to get creative. First, in 2011 he created The Wand tonearm, a striking unipivot design that features a fat carbon-fiber armtube nearly 1" in diameter (below). Art Dudley wrote about The Wand in 2019, and I highly recommend that you read his thoughts, especially about his struggles to set up The Wand.

About four years ago, the stand-alone tonearm market went through a bit of a crisis. First, in December 2019, SME announced that it would stop selling tonearms separately, effective immediately. From that point on, SME tonearms would be available only in combination with SME turntables. . .

Five months later, in May 2020, we received the second blow in this double whammy of bad tonearm news. That's when the Ichikawa Jewel Company of Japan, maker of Jelco tonearms, announced without warning that they were shutting down operations, closing their doors for good. They blamed a combination of an aging workforce, worn-out tooling that needed to be replaced, and the coronavirus pandemic. . .

We lost two key players all at once, but it's not as if we suddenly had nowhere to turn for tonearms. Turntable manufacturers like Acoustic Signature, Clearaudio, Origin Live, Pro-Ject, Rega, and VPI all sell their tonearms separately . . . A number of smaller tonearm specialists have popped up in recent decades: Acoustical Systems, Graham, GrooveMaster, Kuzma, Reed, Schick, Schröder, and at the ultrahigh end, Swedish Analog Technologies. Now we can add Korf Audio to the list.

When I think about landmark years in the history of British hi-fi, 1973 sticks out. Three companies got their start in the first half of that year that went on to become cornerstones of the British audio scene: Linn Products, Naim Audio, and Rega Research. That means they're all celebrating their 50th anniversaries in 2023.

I have found that turntable designers typically fall into one of two camps. First are what I call the obsessive machinists. These are the people with impressive manufacturing chops and a sharp eye for fine detail and precision. For them, making a better turntable usually involves taking what we already know and simply doing it better.

Whether it's a thicker chassis, more powerful motor, more precise bearing, more effective isolation system, or something else, the emphasis is always on stepping things up a notch or two, rather than reinventing the wheel. This obsession can result in some impressive 'tables—some of the most impressive in the world, with awesome attention to detail. But are they the best sounding?

The other camp is what I call the deep thinkers. They approach the task of playing a record from a theoretical perspective and leverage their knowledge of physics to come up with fresh and innovative designs. The results may look unconventional, or even odd at first glance, but when such lateral thinking clicks, it can really push the boundaries of what's possible.

The next time you're preparing to play a record, try doing a little experiment. Once you have the record mounted and spinning but before you lower the stylus into the groove, lower your gaze to just below record level and look for a gap between the platter and the record. It helps if there's a light source or a brightly colored wall behind the platter. You may discover a gap—that very little of the record's playing area is making true contact with the platter mat or (if there is no mat) the platter. Another way to test this is to take a record you don't care much about, put it on the platter, then tap with your finger in the groove area listening for a click as your finger pushes the record down and it contacts the platter surface.

Warps obviously lead to such problems, but even records that appear flat make scant contact with the supporting surface. Turntable and aftermarket accessory designers have recognized this problem for decades.

10. Acoustic Signature's listening room with its massive PBN loudspeaker system.

May has long been one of my favorite months of the year, mostly because it means it's time for the Munich show, the annual gathering of the high-end audio tribe in the Bavarian capital. High End Munich 2023 marked my return to the biggest audio show in the Western world following three years of lockdowns and travel restrictions, so I was eager to get back to the land of Wiener schnitzel and bratwurst.

This year, as an added bonus, I was invited to visit the production facilities of turntable and tonearm manufacturer Acoustic Signature, which is based about 110 miles west of Munich, near Stuttgart.

It's hard to convey the scope of the annual High End Munich audio show to someone who has never attended. Spread out over three floors of a large facility called the Munich Order Center (MOC), the show is notable for how different it is from audio shows in the US. The ground floor is an area about the size of three American football fields, where brands set up professional trade show booths to display their wares. This is a long way from the draped folding tables and back curtain on a rail that defines a "show booth" at most US shows. What you'll find on this level is mostly static displays, although scattered among the displays you'll find prefabricated sound rooms, acoustically designed spaces designed to allow live demonstrations on the ground floor.

My main focus at the show was to try to root out interesting new record-playing gear. I was not disappointed. Here are a few select highlights from what I saw at the show.

In 1928, Swiss engineer and inventor Jean-Léon Reutter created a clock that could run for years without human interaction or any type of external power source. The Atmos Clock required no AC power, batteries, solar panels, or hand-winding. It was able to wind itself by leveraging subtle changes in atmospheric pressure and temperature.

The design was so energy efficient that a single degree of temperature change provided enough power for two days of operation; it would take an incredible 60 million Atmos clocks to equal the power demands of a single 15W light bulb. 95 years later, the Atmos Clock is still being manufactured in Switzerland by Jaeger-LeCoultre, but like most high-precision, Swiss-made instruments, it isn't cheap. Prices start around $7500.

Over the last 40 years, I have set up or serviced literally thousands of turntables, and during that time I have seen a lot of increasingly sophisticated tools become available to help in getting your turntable optimized. I've had my eye on the Shaknspin speed analyzer since it was launched a couple of years ago, and now there's a new Shaknspin2, which promises more accurate results.
