Analog Corner

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.

VPI Industries Voyager phono preamplifier
Following my auditioning of Channel D's Lino 2C current-mode phono preamplifier, back in the world of voltage amplification, here's another phono preamp from another company based, like Channel D, in New Jersey. Probably not since Dynaco manufactured its electronics in Pennsauken has the Garden State enjoyed such riches of analog electronics!

I went everywhere!

Attending the two-day Making Vinyl Berlin B2B conference on May 2 and 3, 2019 was an obvious decision for me, even if Day 1's "Physical Media World Conference" panel discussion was more about optical digital media than it was about analog vinyl.

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.

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.

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.

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.
