Digital Processor Reviews

Ah, domesticity. Just when I had the reference system sounding better than ever, the husband decided to relocate his electric keyboard and music stand, which had been positioned along the right wall of the detached music room, to the dining room in the main house. His reason was rational: While I did the reviewer thing in one space, he'd be free to practice keyboard and sing in another. But what was rational to him screwed with my reference sound and drove me to the brink of irrationality.

One reason Stereophile publishes a FollowUp is when the original review leaves an issue unresolved or where further thoughts would be useful. Such was the case with the magazine's March 2022 issue, which had followup reviews on the iFi ZEN CAN headphone amplifier and ZEN DAC Signature V2 D/A processor ($599/pair). the Pro-Ject Phono Box RS2 phono preamplifier ($1999), and the Canton Reference 7K loudspeaker ($6995/pair).

The January and February 2022 issues of Stereophile feature followup reviews of three products: the darTZeel NHB-18NS Mk.2 preamplifier; the Sutherland Little Loco Mk.2 phono preamplifier; and the Mola Mola Tambaqui D/A processor.

"Resolution can be a tricky thing when it comes to digital," my friend Michael Lavorgna recently told me. "Too much, and my focus shifts from music to sound; too little, and I become less engaged." Lavorgna, a visual artist and proprietor of the online audio-and-music publication Twittering Machines, is one of my favorite people to talk to about records, books, art, and hi-fi. We've been doing it for almost 20 years.

Stereophile often subjects products that have been reviewed to further coverage: sometimes because there was an aspect of performance that needed further investigation; other times because there was a controversial finding. Three recent followups concerned the Ayre Acoustics EX-8 2.0 Integrated Hub amplifier that Ken Micallef reviewed in the November 2021 issue; the Accuphase DG-68 Digital Voicing Equalizer that Jason Victor Serinus reviewed in August 2021; and the Zesto Leto Ultra II line preamplifier that Ken Micallef reviewed in February 2021.

Playlists embody who we are. We use musical affinities to understand (or at least categorize) others, not only as evidence of their aesthetic discernment but also of their emotional and political affiliations, which amount to an entire worldview. In other words, the database of favorite music that we carry around in our brains is no laughing matter. So, one of the most unexpected—and rewarding—things that can happen in music fandom is a complete and sudden inversion of one's beliefs. Which brings me to the perennially touchy subject of Steely Dan, a band that cleaves the ranks of listeners like a gold-plated katana.
