Phono Preamp Reviews

The first audiophile I met lived near a sewage treatment plant on the outskirts of Moscow. It was a few months after the Soviet Union collapsed, in 1992, when I was a college senior, and I recall walking with my father to his home past block after block of the identical dingy white tenements that encircle most Eastern European cities.

If I hear it, is it real?

If your ears see,
And your eyes hear,
Not a doubt you'll cherish—How naturally the rain drips
From the eyes!—Bujutsu Sosho

The more audio gear I review, the more fascinated I become by the fact that as I listen to recorded music, I can close my eyes and see musicians on the stage at Carnegie Hall, or djembe drummers in a desert by a tent, or a bass note penetrating the Milky Way. What a gift of consciousness. And what a great hobby it is that focuses my attentions in this manner.

Whenever I do turntable-setup seminars, I complain to the participants about the lack of cartridge-pin diameter and clip-opening standards. Anyone who does their own setup has experienced it: The connection is too tight or too loose. Forcing the clip onto the pin usually results in a broken-off clip that most end users don't have the soldering skills needed to repair; in the worst case, it can even result in damage to the cartridge when you try to remove the clip from the pin.

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.

Years ago, at a San Francisco Audiophile Society gathering, I was lucky enough to spend time with the late, brilliant electrical engineer Roger Modjeski, whose Music Reference RM-200 Mk.II hybrid stereo tube amp is among my most prized hi-fi treasures. I asked him what he knew about transimpedance phono preamplifiers. He grabbed a piece of paper and a pencil and drew a detailed transimpedance phono preamp circuit, quipping, "These have been around forever, but until recently no one has paid much attention to them."

Michael Fremer wrote about the Paradox phono preamplifier in the March 2022 Analog Corner, Jim Austin reviewed the CH Precision D1.5 CD/SACD player/transport in March 2022, and Herb Reichert included the EJ Jordan Marlow standmount speaker in his April 2022 Gramophone Dreams column. All three products get further coverage in Stereophile's May 2022 issue.

One privilege of being a Stereophile columnist is the opportunity to cover products from smaller, less well-known manufacturers, including those that don't have wide enough distribution to qualify for a full review. One such company is Victorville, California–based Paradox. I'd never heard of them until I received an email from Terence Robinson, the company's owner. The email included a description of a phono preamplifier that so intrigued me that I asked for a review sample.
