Digital Processor Reviews

My late father-in-law used to say that life is like a roll of toilet paper. The closer you get to the end, the quicker it passes. I was reminded of that when I was asked to review Bel Canto's new e1X DAC/Control Preamplifier ($6800). It didn't seem that long ago that I favorably reviewed the Minnesota company's e.One DAC3, but Google told me that it was 15 years ago! "Other than the jitter performance via its USB input, the Bel Canto e.One DAC3 is the best-measuring digital component I have encountered," I wrote in November 2007 (footnote 1), adding that it "offers some impressive audio engineering in both the digital and analog domains."

My little corner of Brooklyn happens to have a terrific little record shop. I like it for the usual reasons: well-chosen merchandise, fair prices, fun music on the speakers while you browse. But I like it just as much because great record stores tend to resemble one another in more idiosyncratic ways, and this one has the earmarks of the great record stores of my youth.

Three high-performance products were subjected to second opinions and/or measurements in recent issues: Channel D's Lino C 3.3 phono preamplifier, Mola Mola's Tambaqui D/A processor, and Pass Labs' XP-32 line preamplifier.

The increasing prominence of Blu-ray explains why a device to extract audio from an HDMI stream has become necessary. At first, Blu-ray players had HDMI outputs for video and audio, but to speed their adoption, they also sported analog audio outputs to help users who had older AV receivers (AVRs). Bye the bye, those audio outputs were pared off.

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.
