Phono Cartridge Reviews

Cavitation revolutionized record cleaning more than a decade ago, when Reiner Gläss's Audiodesksysteme introduced its original fully automatic machine. Mr. Gläss's innovative machine, which automatically spun the record in ultrasonically cavitated water, then dried it with fans, at first was plagued with reliability issues, and because it is sealed, it was not easy to repair.

AVM Audio, which has been in business since 1986 (footnote 1), chose last year to enter the turntable market with two models that reflect the company's brushed-aluminum/blue LED visual aesthetics.

It doesn't take a forensic turntable scientist to figure out who manufactures both of those turntable models. Clearly, Pro-Ject does (footnote 2)—although some audiophiles might recognize only a few key parts. Other elements, especially the two different tonearm models, may appear unique to AVM, having been built to their specs.

We're 30 years into a cartridge design revolution, particularly at the top end of the market, where manufacturers charge upward of $10,000 for their best efforts: prices that well-off consumers have amply proved they are willing to pay. There doesn't seem to be an innovation end in sight.

How goes your quarantining? Honestly, my life hasn't changed much here. I'm locked in the basement as usual, happy to have a good audio system and overwhelmed by my musical choices. Other than minimizing shopping expeditions and wearing a mask, the biggest change in my life is a spike in requests from readers for upgrade advice. I've never been so busy answering reader emails.

We tested two samples of the ADC-1 phono cartridge, both of which were taken from a dealer's stock. One was a demonstrator that had been in use for some months. The other was brand new, right off the shelf. Both were tested in an Empire 98 tonearm and in a Gray 108-C tonearm with its damping lightly adjusted, but results with both cartridges were for all intents and purposes identical in both arms.

While the AT-OC9 bears the Audio-Technica logo, you won't find a sample of this moving-coil cartridge at your friendly Audio-Technica dealership. The US distributor of Audio-Technica products has apparently decided that their market does not include high-end cartridges. A quick perusal of the latest Audio directory issue (October 1988) lists the most expensive AT cartridge at $295, with no moving-coils in sight. When I first heard of the AT-OC9, the only reasonably accessible source, short of Japan, was Audio-Technica in the UK. A quick phone call and follow-up letter resulted in a review sample. Since that time, Music Hall in the US importers of the Epos loudspeakers, among other items) has begun importing the AT-OC9 (along with the less-expensive AT-F5). Mail-order company Lyle Cartridges also stock it, I believe.

The ceiling remains, but the floor has changed: Benz-Micro continues to offer a selection of rather expensive phono cartridges, including their well-established LP Ebony ($4700) and Ruby 3 ($3000) models. But in recent years, my attention has been drawn by the succession of budget Benzes: first, the Gliders ($795), then the ACEs ($550), and now the MC20E2-L ($199).
