Phono Preamp Reviews

My DACs are taking naps. I have not played music from a digital source in at least 12 weeks. I'm having too much fun playing records from the '50s and '60s with period-correct phono cartridges and listening to 100-year-old 78s at the Hot Club of New York.

My oldest aural memory is my mother singing nursery rhymes to send me off to sleep. After that, it's vinyl records. Being the third child, I benefited from a constant stream of audio-related hand-me-downs, starting with a 1960s kiddie phonograph and a pile of well-worn records from my older brothers.

One of the pleasures of reviewing—and also using—products from Pass Laboratories is an encounter with Nelson Pass's writing, which can usually be found in the owner's manual and is always competent, insightful, and sometimes funny. How often do you get real pleasure and insight from reading an owner's manual?

Pass Labs has a lot of owner's manuals online. Reading through one, I encountered the following passage; you'll find the same or similar language in other manuals and on the Pass Labs website. I present it not only because I admire it and agree with the philosophy it expresses but also because it captures the spirit of the product under review—the XP-27 phono preamplifier ($12,075 in silver)—at least as I've experienced it during an extended review period. Here it is, quoted at length with some slight adjustments to make it consistent with Stereophile's editorial style...

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."

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.

Phono preamplifiers could be compared to children as viewed by a previous generation of adults: They are expected to be small in stature, and they should stay out of the way, seen but not heard and maybe not even seen. With the simpler models typically encountered at lower price points, there's little to do except "set it and forget it."
