Unpacking and installing a new component is always cause for excitement, even if one does it with almost mechanical regularity, and the anticipation is greater when the component is from a manufacturer of almost mythic reputation. So when John Atkinson asked if I'd like to audition Nagra's new PL-L preamplifier, I feigned calm as I accepted the assignment, even while remembering those years in college radio when I had to schlepp big Ampexes and Maggies. The sexy, portable Nagras were the stuff of dreams. Finally, I thought, I'd get my hands and ears on one.

I had a wonderful audio moment the other night. It was late in the evening, after a long day. I was standing in the middle of my makeshift listening room—Trish's dining room—and in spite of the fact that we were moving in just a few weeks, I'd just unpacked and set up my combo of VPI TNT Mk.V-HR turntable and tonearm with Grado Statement cartridge and dug a box of LPs out of the stacks in the garage. I cued up Dave Brubeck's Time Out (Columbia/Classic CS 8192), and the first notes of "Blue Rondo à la Turk" froze me in my tracks.

"It took long enough," as I said to Larry Fish and Roger Stockholm.

I like stories with happy endings.

The L2 Reference sits at the top of Lamm Industries' preamplifier line. According to the manual, its "unique" circuitry uses specially selected, superlinear, high-voltage MOSFET transistors that ensure class-A operation from input to output, with no overall negative feedback at any stage. All stages, including the high-current output buffers, are single-ended.

As part of my employer's never-ending attempts to transform me from an engineer into a manager, I am constantly being sent to seminars and courses, some of which are eminently practical—like "Managers and the Law," which taught us how to avoid getting ourselves and our company sued. Others are more esoteric, like a recent seminar on "paradigm shifts." A paradigm shift, we were told, is a fundamental change in the way we look at things, arising from a change in a belief so inherent that it's unconscious.

I've been attending the annual Consumer Electronics Show for years, and usually come away with the impression that there are too many "me-too" products. I see a numbing similarity of approach of manufacturers within a chosen discipline: solid-state power amps in black and silver bristling with heatsinks, single-ended triode amps with their glow reflecting from bronze or wood panels, MCPU/DSP-centered devices with sleek, flat cases and intimidating remote controls, etc.

There's a whorish aspect to reviewing that some readers and industry critics never tire of mentioning, as if they've stumbled onto some great revelation: that we writers seem to flit from new product to new product, sometimes gushing like cracked fire hydrants over one amplifier one month, only to gush over another amp the following month.

It's a reviewer's privilege to be able to switch back and forth between tube and solid-state gear (or combinations thereof) as the mood or the assignment moves him. Still, I find I'm inevitably drawn back to the Epicurean delights of triode tube gear. When done right, there's an alluring musicality to it, like the breath of life. However, in any tube vs solid-state contest, the relative tradeoffs between tone and resolution—sweetness and articulation, euphony and frequency extension—must be taken into consideration.

Audio Research's first 21st-century, audiophile-quality line-stage preamplifier combines retro-tech vacuum-tube amplification and power-supply circuitry with innovative, remote-controlled gain, balance, tape monitoring, and signal routing. The price is also 21st-century: $9995. As in ARC's Reference phono section, the Reference Two's pair of vertically mounted circuit boards results in a single, relatively tall chassis.

Ideally, through the medium of a synergistically balanced set of high-resolution components, we seek to re-create an acoustic event with a palpable sense of realism—as in timbre, dynamics, room cues, and dimensionality. Have I ever experienced a system commensurate with the experience of sitting 12th-row-center at Carnegie Hall for Boulez conducting Stravinsky? Close, but...

This is an era in which products and websites are "launched," but in the past two years Herron Audio has sort of oozed its way into the public ear. With little visible promotion or splashy advertising, Herron is now spoken of within an ever-widening audiophile circle.

We thought Audo Research's previous-model SP-2C (footnote 1) was excellent, but this is even better—the closest thing available, in fact, to the ideal straight wire with gain. Our sample had a minor glitch—there was a slight "plop" if you rotated the tone controls rapidly—but we could find nothing else about it to criticize. Currently, by far the best preamplifier than money can buy. And would you believe it uses tubes (at reduced heater voltage, for extended life and cooler operation)!

Almost two years ago, Conrad-Johnson's Lew Johnson came to Santa Fe while visiting his western dealers. We were chatting about acquaintances in the industry as I showed him the new house I'd barely moved into when he spread a blueprint across a stack of record boxes and showed me a design for a new product.

One memorable afternoon during HI-FI '97, Kathleen and my pudgy little self were hustling down the crowded corridors of San Francisco's venerable St. Francis Hotel, trying to make the Nagra press event. The Nagra suite was crowded with buzzing journalists, their anticipation palpable—the new Nagra PL-P preamplifier was about to enjoy its official debut. Suddenly the door to the demo room flew open. The vacuum created by the stampeding hordes nearly sucked the hors d'oeuvres off the table.
