Phono Cartridge Reviews

The days were long, the strawberries ripe, but it wasn't quite summer. It was, however, a perfect night for Otis Redding and Carla Thomas singing the Lowell Fulson–Jimmy McCracklin classic "Tramp," on a 7" 45rpm single (Stax 45-216).

Otis: What you call me?

Carla: Tramp! You don't wear continental clothes, or Stetson hats.

A few years ago, Leif Johannsen, Ortofon's chief officer of acoustics and technology, was tasked with designing new products to commemorate the company's 100th anniversary, in 2018 (footnote 1). Ten years ago, to celebrate Ortofon's 90th, he came up with the radical A90 moving-coil cartridge, which used Selective Laser Melt (SLM) technology to laser-weld together microparticles of stainless steel, layer by layer, to produce a 3D-printed metal body whose shape would have been impossible to machine.

Among the electrically connected, the phrase short circuit induces panic and horrific images of tripped breakers, blown fuses, acrid blue smoke, and melted circuit boards. Nonetheless, near short circuits are becoming popular among the analog set. Moving-coil cartridges of an inductance and impedance so low they're nearly short circuits are now more common, thanks to powerful neodymium magnets that help produce more and more electrical output from fewer and fewer turns of coil wire. Perhaps the most extreme example of this is the Haniwa HCTR01 Mk.II cartridge, which has an internal impedance of 0.4 ohm and an inductance of 0.3µH.

Peter Ledermann, founder and chief designer of Soundsmith, Inc., began his adventures in phono cartridges by reverse-engineering Bang & Olufsen's Moving Micro-Cross moving-iron cartridges for customers B&O had abandoned when it got out of the LP player business, and putting them into production. The B&O cartridges were of the direct plug-in variety; once they were no longer made, a worn or broken B&O cartridge would render a B&O turntable unusable.

On at least one occasion that I can recall—in 1996, in the early days of Listener magazine—a US publicist for the Japanese manufacturing company Denon told me that they planned to discontinue their DL-103 moving-coil phono cartridge, an enduringly popular model that had been in production since 1962 (footnote 1). At the time, neither the DL-103 nor any of their other cartridge models appeared on Denon's US price lists, and neither English-language promotional materials nor even a basic spec sheet was available to American consumers or press.

Brooklyn-based Grado Labs has been in business for 64 years, manufacturing moving-iron phono cartridges, headphones, and, for a while, even a unipivot tonearm with a wooden armwand, as well as the sophisticated, S-shaped Signature Laboratory Standard arm.

How can you tell a classic product from the hi-fi hoi polloi? One sure sign is when third-party developers spring up around the thing, offering parts and service intended to maximize its performance—or just to keep it on the road. Thus regarded, a few true classics emerge: Quad's ESL and ESL-63 loudspeakers. Altec's 802 and 806 compression drivers. The Linn LP12 and Garrard 301/401 turntables. The Rega RB-300 tonearm and its direct descendants.
