I'm waiting for a bypass.

My heart did not attack me. My arteries aren't clogged. I'm awaiting an electrical bypass to save my audio system's life.

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!

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.

I'm an audiophile and live in North America—seems like a perfect fit for the Facebook group Audiophiles - North America, right? Wrong!

On my first visit, I noticed that a group member had asked for speaker cable suggestions. Another member posted a picture of a 100' spool of 16-gauge lamp cord costing $14, accompanied by the suggestion "This is all you need." The implication: That's all anyone needs, because cables are "snake oil.

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.

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.

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.

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.

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.

Let's begin by discussing what SAT's XD1 Record Player System is not: It is not a Technics SP-10R in a sci-fi–inspired plinth—although the XD1's engine does begin life as the SP-10R's basic drive system, which is stripped down to a handful of essential components, reimagined, reengineered, and rebuilt to much higher mechanical standards.

Judging by VPI's new HW-40 direct-drive turntable, middle age well suits the company that Harry and Sheila Weisfeld started 40 years ago in their Howard Beach, Long Island, basement.

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.

Back in the 1990s, my friend Nick Despotopoulos and I published an article in The Tracking Angle titled "Zen and the Art of Record Cleaning Made Difficult," describing author Michael Wayne's record-cleaning methodology. That regimen, like the article itself, was the most comprehensive one I knew of at the time.

In place of my usual Wilson Alexxes, a pair of small (though very fine) two-way speakers has been in my system this past month: the Marten Oscar Duos I review elsewhere in this issue. Without my usual reference speakers in the system, I didn't feel comfortable covering anything that affects sound quality for this column, so, with the exception of one item—the first—this column covers accessories that don't require sonic evaluation.
