Audacious Audio

Why bother with three phono preamps most of us can't afford? For the same reason the enthusiast automobile magazines cover the newest Ferraris and Lamborghinis: just reading about them is fun.

Ideally, LPs should be played with the pickup stylus remaining tangential (ie, at a 90° angle) to the groove—just as the lacquer from which the LP was ultimately stamped was cut in the first place. Over the years, many attempts have been made to accomplish this. Back in 1877, Thomas A. Edison's original machines tangentially tracked his cylinders, but Emil Berliner's invention of the flat disc put an end to cylinders altogether. In the 1950s, a number of companies marketed so-called "tangential" trackers that used dual arms, based on conventional pivoting arrangements, to change the angle at which the headshell was mounted as it moved across the LP side. In 1963, Marantz introduced the SLT-12, which used a plastic pantograph to move the stylus across the record surface. Garrard's Zero 100 pivoting arm controlled its independently pivoting headshell with a bar that extended from the main bearing of the tonearm.

If you've followed their story here and elsewhere, you probably know that Tokyo's Shindo Laboratory (footnote 1) has a reputation for defying the two most monolithic of all high-end audio commandments.

Stereophile's founder, the late J. Gordon Holt, always had a thing for horn loudspeakers, feeling that these archaic beasts offered a "jump factor" that could never be rivaled by conventional, direct-radiating designs. A horn drastically increases the efficiency with which electrical power is converted into acoustic power, which means that for a given sound-pressure level, a smaller amplifier can be used compared with a direct-radiator, and that all distortions, both electrical and mechanical, can theoretically be much lower. Yet outside of a small circle of enthusiasts, horns never got much of a following in high-end audio, and as high amplifier power became plentiful and relatively cheap, horns largely disappeared from domestic audio use (except in Japan).

This massive, two-box beauty from Denmark costs $60,000, and I wish I could tell you it wasn't really better in most ways than the already outlandishly priced and sonically superb Boulder 2008. I can't.

While headphone listening remains secondary to that of loudspeakers for most serious listeners, it's still an important alternative for many. And while good conventional headphones exist, electrostatics are usually considered first when the highest playback quality is required. As always, there are exceptions (Grado's headphones come immediately to mind), but most high-end headphones are electrostatic—such designs offer the benefits of electrostatic loudspeakers without their dynamic limitations.

Here I listen to examples from two other companies, each known for its headphones since Pluto was a pup.

Snickering was heard from the major consumer electronics purveyors when California Audio Labs came out with the original">http://www.stereophile.com/cdplayers/654">original Tempest, their first CD player using tube output stages. But not from the audiophile community. It was, all things considered, an inevitable product; I'm certainly not the only one who wondered—before the emergence of California Audio Labs—who would be the first to build such a unit. The obvious candidates were Audio Research or Conrad-Johnson. But those companies apparently read the audio tea-leaves and, perhaps perceiving the early high-end hostility toward the new format, apparently decided to bide their time. (With regards to tube players, they're still biding it, though C-J has had a prototype player up and running for some time.)
