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.

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.

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.

How goes your quarantining? Honestly, my life hasn't changed much here. I'm locked in the basement as usual, happy to have a good audio system and overwhelmed by my musical choices. Other than minimizing shopping expeditions and wearing a mask, the biggest change in my life is a spike in requests from readers for upgrade advice. I've never been so busy answering reader emails.

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.

At the 2017 Hong Kong High End Audio/Video Show, I found myself sitting next to a turntable manufacturer who shall remain anonymous. A Reed Muse 3C turntable ($20,000) with 3P tonearm sat on a display table across from us.

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.
