Phono Preamp Reviews

Not that many years ago, it seems, every sound crew in Hollywood and around the world recorded production sound using a compact, open-reel analog tape recorder made by Nagra. The first iteration of the Swiss-made machine appeared in the early 1950s. Shortly thereafter, with the addition of an inaudible recorded tone that allowed easy syncing to picture, the Nagra recorder became the industry standard, and remained so through the 1980s. To this day, Nagra's line of audio products retains the look of those early recorders.

Basically, I have to admit that I am a Valvophobe. I would give you the dictionary definition of that word, but it has been sealed in a mayonnaise jar on Funk and Wagnall's porch since . . . Anyway, you get the idea. A Valvophobe is someone who doesn't like tubes in their 1986 stereo systems.

According to Parasound's founder and CEO, Richard Schram, the Halo JC 3 began as a phono-preamp retrofit for the JC 2 line stage, with separate small circuit boards for each channel. The smaller the board, the better, Schram says, so as to attract less noise than do larger boards, whose many copper traces can act as antennas.

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...

You think Watergate was a momentous break-in? You should hear what a good electronic Rolfing does to the sound of this meticulously built, full-sized, full-featured, and full-priced ($3495) phono section imported from New Zealand by Fanfare International. Out of the box, the Plinius M14 sounds like what it looks like: all silvery, hard, and steely. Just leaving it powered up doesn't do the trick, nor does playing music through it—unless you're prepared for endless hours of truly bad sound before the sonic clouds begin to break.

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."

PS Audio's first product, back in 1973, was a standalone phono stage; more recently, their PCA-2 preamp had an optional phono board. The GCC-100http://www.stereophile.com/solidpoweramps/106ps">GCC-100; integrated amplifier that I review this month has no room inside for a phono board, so they've gone back to producing a separate phono stage: the GCPH ($995). Like the other products in PS Audio's current line, this one is based on the Gain Cell, one module on the input side connecting to the cartridge, followed by a passive RIAA curve (with a claimed accuracy of 0.1dB over the 40dB range of the curve), and another Gain Cell on the output side.
