Tonearm Reviews

For a phono cartridge to generate current and voltage, something must move: a coil of wire (as in a moving-coil cartridge), or a magnet (as in a moving-magnet type), or a tiny piece of iron (a moving-iron type). In those rare cartridges that depart from the electricity-generating principle of the ones described above, it can be a displacement-measuring device in which a moving shutter modulates a light source to vary a supplied voltage (as in an optical cartridge), or one in which voltage is modulated when a tiny chip of silicon crystal is squeezed by a moving element, which varies the chip's electrical resistance (as in a strain-gauge cartridge). But regardless of what it is that moves in a cartridge, something has to.

In 2013, when I first wrote about it (footnote 1), the TechDAS Air Force One ($105,000) was that company's best and most expensive turntable; it joined the handful of products that have earned an A+ in our semiannual Recommended Components feature—a rating that remained in place for six years. But too much time has passed since the Air Force One was auditioned by a Stereophile writer, so it has now fallen from that list.

German engineering acumen and machining excellence—acknowledged and admired worldwide—are nowhere to be seen on AMG's flagship Viella Forte turntable and new 12JT tonearm. That's because, while what's on the surface is cosmetically and mechanically well-turned, the design features and precision engineering that set AMG's turntables and tonearms apart are inside and hidden from view.

Lately it seems that the more Rega charges for one of its turntables, the less you get—and from Rega's performance perspective that's a good thing.

While some turntable designs pile on the mass, hoping to tame resonances and better isolate the record from the outside world, Rega has long advocated ultralow-mass designs. What's up with that?

Money, that unreliable buyer of happiness, has at times proven effective at delivering good sound. It can buy other things, as well: Audiophiles can swap cash for products that function as objets d'art, as status symbols, or even as canny investments.

But—do you think money can buy peace of mind for the audio enthusiast who frets over binding voice-coils, leaking capacitors, drifting resistor values, oxidizing connectors, aging or incorrectly biased tubes, and that most pernicious worry of all, distortion and premature record wear from incorrectly aligned phono cartridges? Sadly, most of those neuroses, some quite reasonable, remain unaddressed by cash almighty.

Peter J. Walker (1916–2003), founder of Quad Electroacoustics and designer of some of the most well-regarded products in the history of domestic audio, famously believed that a properly designed audio-frequency amplifier should have no sound of its own. As for suggestions that his Quad II amplifier (1953–1971) sounded better than most, Walker was unmoved: "We designed our valve amplifier, manufactured it, put it on the market and never actually listened to it."

I first learned of the Kuzma Stogi at the 1993 Winter CES in Las Vegas. In VPI's room at the Sahara, a portly, black tonearm was sitting proudly atop the new VPI TNT Series 3 turntable. Pointing straight at me from the center of its massive, exceptionally stout frame was a tapered armtube the diameter of a swollen thumb. The fact that this unknown (to me) tonearm was chosen to sit atop a turntable as respected as the TNT told me I was looking at a serious new product. VPI's Harry Weisfeld was standing nearby, beaming as usual, to answer the barrage of questions that sprang from my lips as I leaned over for a closer inspection. Who? What? Where? When? Why? How much?
