Phono Preamp Reviews

Sometime around 483 BCE, in Kushinagar, the capital of the Malla Republic in what today is the Indian state of Uttar Pradesh, an aristocrat named Siddhārtha Gautama—known better to us as the Buddha, or the Awakened One—passed away. For 45 years, he had wandered the North Indian River Plain teaching a method of overcoming ignorance, craving, and the cycle of death and rebirth to a growing community of followers.

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.

Gold Note's $11,999 PH-1000 is by a considerable margin the most sophisticated, most configurable phono preamplifier that any audio manufacturer has ever produced, at least that I know of. Remarkably, considering all that flexibility and sophistication, using and adjusting the PH-1000 is straightforward.

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.
