Pass Laboratories XP-27

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.

Pass Laboratories XP-27

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: "For a very long time, there has been faith in the technical community that eventually some objective analysis would reconcile critical listeners' subjective experience with a repeatable laboratory measurement protocol. Perhaps this will ultimately occur, but in the meantime, audiophiles largely reject bench specifications as an indicator of audio quality. This is appropriate; the appreciation of audio is a completely subjective human experience. We should no more let the numbers define audio quality than we would let chemical analysis be the ultimate arbiter of fine wines.

Measurements are certainly critical, they can and do provide a measure of insight, but are no substitute for human judgment of that which is pleasant.

"As in art, classic audio components are the results of individual and collective efforts that reflect a coherent underlying goal and philosophy by the major participants. If successful, they make both a subjective and an objective statement of quality, which is meant to elicit appreciation in the final product. It is essential that the circuitry of an audio component reflects a philosophy which addresses the subjective nature of its performance first and foremost.

BRILLIANT CORNERS - I have a day job at a museum. One of my favorite things about working there is taking the elevator from my office down to one of the floors open to the public; I walk into the galleries through a discreet panel in the wall. This makes me feel like I'm in one of those horror-movie manors with a tunnel concealed behind a bookshelf. Sometimes I startle people, which I kind of enjoy.

EDITOR'S PICK - RECORDING OF THE MONTH

The record business was awash in money and power. Vinyl LPs were still five bucks, and while the pressings could be suspect, the music-buying public still snapped them up en masse.

The Butthole Surfers wipe out

REVINYLIZATION - Music's lunatic fringe drifts further out every hour. As it should. In this century, with computers playing an ever-larger role, music continues to fragment and become infinitely more varied. This splintering is either the essence of what keeps it relevant as an art form or something profoundly disturbing, to be hated and feared.

AURAL ROBERT - The least surprising story in music today is the inevitable passing of irreplaceable talent. Tenor saxophonist Benny Golson died at age 95 the day I finished this salute to another fallen star, Southern California singer/songwriter John David \"JD\" Souther.

PS Audio Aspen FR5 - LOUDSPEAKER

I remember the first PS Audio product: a simple phono stage. It was so simple - a passive RIAA eq filter flanked by a pair of primitive op-amps - that when the schematic was made public, I built one myself; I was in the midst of my DIY years. I thought it was, to use a word from that time, nifty.

TEAC UD-701N - STREAMING PREAMP, D/A CONVERTER

In Gramophone Dreams #88, I described the sound of TEAC's VRDS-701T CD transport as \"dense and precise in a way I had never previously heard from digital.\" I went on to explain, \"by dense, I mean there was a tangible corporeality effected by seemingly infinite quantities of small, tightly packed molecules of musical information.\"

Sonus faber Sonetto V G2 - LOUDSPEAKER

Here's a hard truth: A written review of a full-sized speaker any speaker, really-is, at best, semi-useful. We all listen differently, we have different musical tastes, our system electronics are different, and our listening rooms vary a lot. You will gain a general picture of a speaker's capabilities and foibles from John Atkinson's measurements, and I can tell you how the speakers sound to me, in my room. But that's it. You need to hear them for yourself before making a buying decision. The best I can do is tell you how my music brain felt when the speakers were in my house and making music.

STEREOPHILE'S 33RD ANNUAL - PRODUCT OF THE YEAR AWARD 2024

When Stereophile's Product of the Year Awards were first published, in 1992, we decided that unlike some other publications and their awards schemes, we would keep the number of categories to a minimum. That way, we would avoid what the late Art Dudley once described as the \"every child in the class gets a prize\" syndrome.

Moon 861 - POWER AMPLIFIER

It is unusual to begin a review with a detailed discussion of setup. But setup protocol for the Moon 861 power amplifier ($22,000 each), the top-level amplifier in the North Collection from Moon, which I reviewed bridged in mono, proved crucial to its sound.
