Analog Corner

Something's definitely happening at the house of Yoshio Matsudaira. The legendary gentleman, whom I've never met or corresponded with, manufactures cartridges for his own brand, My Sonic Lab, as well as for others, including Air Tight. Over the past few weeks, more than a few readers have asked me to review or at least listen to the latest My Sonic Lab cartridge, the Platinum Signature.

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.

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.

As I was doing a final edit on this column, I received very sad news from Leif Johannsen, the chief officer of acoustics and technology for cartridge manufacturer Ortofon A/S: Kim Petersen, described by Johannsen as his "right hand and new cartridge design and listening partner" and the company's "top cartridge expert," passed away suddenly at age 52.

Since acquiring SME in late 2016, Ajay Shirke's Cadence Group has moved cautiously. First, it revamped and cleaned up the company's somewhat chaotic worldwide distribution. More recently, the new owners eliminated from the bottom of the line the SME Model 10 turntable, introduced in 2000.

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.
