Audacious Audio

Designer Dr. Roger West got his first taste of electrostatic transducers many years ago during a stint with Janszen (remember the Janszen tweeter?). To realize the potential of the full-range electrostatic loudspeaker (ESL), he and Dr. Dale Ream formed a new company dedicated to ESL research and development. West describes this company, Sound-Lab Corp., as "the electrostatic speaker specialists."

I had been anticipating getting to audition a pair of TAD loudspeakers in my system since the introduction of the original TAD Model-1, in 2003. It was designed by Andrew Jones, who had recently assumed the mantle of chief designer at Technical Audio Devices Laboratories (TAD), at that time a subsidiary of Pioneer. Although TAD dates back to the mid-1970s, its research and development efforts had been focused on the professional sound market, something that continues. Jones came from a long line of speaker innovators at KEF and was assigned the goal of developing state-of-the-art speakers for the domestic market.

The advertisements run by Colorado manufacturer YG Acoustics in 2008, when it launched its flagship loudspeaker model, the Anat Reference II Professional, unequivocally claimed it to be "The best loudspeaker on Earth. Period." They caused a stir. The YGA speaker cost $107,000/pair at the time of Wes Phillips's review in the March 2009 issue. Wes didn't disagree with the claim, concluding that, "Like my pappy used to say, it ain't braggin' if you can actually do it."

In the early 1970s, Stereophile's founder, J. Gordon Holt—a man I used to describe, with all due respect, as having been clothed by the haberdasher to the homeless—said that Audio Research's SP-3 tubed preamplifier was "the closest thing available, in fact, to the ideal straight wire with gain" ie, it would amplify the signal without editorializng in any way. Back then, the SP-3 cost $595. Today it would cost around $3500. But TAD's C600 dual-mono, solid-state, balanced preamplifier costs more than 10 times that: $42,000.

In April 1987, Anthony H. Cordesman had mixed feelings about the Mod Squad Passive Line Drive System Control Center. (Read his review here.) Introduced in 1984, the Line Drive offered volume and balance controls, five line-level inputs, and switching and monitoring for two tape decks. You didn't plug it into the wall; it provided no gain. Was it even a proper preamp? (footnote 1)

AHC demurred. "I'm not sure that I'm ready to advise anyone to take the risk of not buying a unit with a top-quality phono stage, no matter how well CD or DAT perform," he concluded, between commenting on Middle East wars.

The challenge is biblical in character, if not in scope: A half year after railing, in these pages, against our industry's overabundance of products that cost more than $20,000, fate has given me such a thing to review.

It was the strangest thing. In the fall of 2008 I was comparing Ayre Acoustics' then-new KX-R line preamplifier with no preamplifier at all—I was feeding the power amplifier directly with the output of the Logitech Transporter D/A processor. (Levels were matched for the comparisons, of course, made possible by the fact that the Transporter has a digital-domain volume control.) Being a rational being, I knew that the active circuitry of a preamplifier, as well as the extra socketry and cables, would be less transparent to the audio signal than a single piece of wire. I wanted to determine by how much the Ayre preamp fell short of that standard.
