Analog Corner

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.

The catastrophic February 6 fire at the factory where Apollo Masters produced LP-mastering lacquers—flat aluminum discs covered with nitrocellulose lacquer—will be old news by the time this column gets to you, but the repercussions of the loss will be ongoing for at least the next year and probably beyond.

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.

The two biggest sonic jolts I've experienced involving phono preamps were from two very different ones: the Petr Mares's Connoisseur 2.0 and Boulder's 2008, which was reviewed in the July 2002 Stereophile. The first was hand-built, single-ended, housed in a wooden case, limited to 100 units, and, when I got to hear it in the mid-1990s, cost around $6000, or about $10,000 in today's dollars. The other was a feature-laden, double-chassis monument to flexibility and surface-mount high technology. It featured beautifully finished, flush-mounted mirrored buttons your fingers just wanted to press.

I was planning to ignore the big three oh oh—my 300th Analog Corner column—and go about my normal business of covering an assortment of new analog gear and accessories. There's an abundance of those today, 25 years after the publication of my first column. Back then, there was far less to write about: Vinyl was on life support and headed for the obsolete-music-format trash heap atop a pile of Elcasets and 8-track tapes.

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.
