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.

Lately, there's been too much gear worth covering and not enough space to cover it in. So this time . . . less think-piece filler and more hardware!

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.

Haniwa's Dr. Tetsuo Kubo is an interesting fellow. If you go to shows, domestic or overseas, you've possibly encountered him in his room a space known for being strewn, shrine-like, with LPs that once belonged to The Absolute Sound's founder, the late Harry Pearson: Dr. Kubo was a fan.

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?

Lately, current amplification–based moving-coil phono preamplifiers have gotten a great deal of well-deserved press. For years, Haniwa's Dr. Kubo has been designing and selling super–low-internal-impedance cartridges because such cartridges work best with such devices. He has also been designing and selling his own current-amplification phono preamplifier.

I feel compelled to repeat here an eerie occurrence I related a while back on AnalogPlanet. I reviewed, in the February 1999 Analog Corner column, the Cartridge Man's Digital Stylus Force Gauge, which back then sold for $299.

I still have it, but a decade ago, the battery stopped taking a charge. I put it aside, planning to replace the battery someday.
