Audacious Audio

The audiophile does not pursue music reproduction because it is useful; he pursues it because he delights in it, and he delights in it because it is beautiful. If music were not beautiful it would not be worth knowing, and if music were not worth knowing life would not be worth living.

My apologies for corrupting the well-known statement by French mathematician Jules Henri Poincaré (1854–1912), in which he described his relationship with science and nature. But substituting audiophile for scientist and music for nature, I feel the sentiment expresses what drives many audiophiles to the extremes for which mere mortals often chide us.

The Jadis Eurythmie speakers ($37,000/pair) arrived in a multitude of oversized boxes. Importer Northstar Leading the Way's Frank Garbie dragged them into our downstairs lobby and broke them open, elevatoring the individual modules up to our door. This happened on one of my office days, but Kathleen pushed me out the door in the morning with a "Don't worry cherie, I can handle it..." She phoned in periodic updates on Garbie's progress. Remember that old Stan Freberg routine? "I got it, I got it...I don't got it!" I arrived home just in time to hook up the amps.

A recent (unpublished) letter to the editor argued that the reference for audio perfection is the sound of real instruments in a real space. The writer claimed that, since the art and/or science of audio is advancing, and because it is a "scientific truth" that the closer you get to perfection, the less divergence there is components, that therefore there should be less difference in sound among the components listed in Class A of Stereophile's "Recommended Components" than among those in Class B, much less Class C. This should be true of loudspeakers, he said, but even more true of top-rated amplifiers, since "they inherently have less divergence."

For a manufacturer to squeeze money from the stone that is my CD-player budget, his products would have to be both exceptional and affordable. And as long as I'm reporting from Fantasyland, I'll ask that they also be obsolescence-proof.

The phenomenon of the "singing flame" has been known since the 19th century. Place electrodes either side of a flame and, if you apply a high enough audio-modulated voltage to those electrodes, the ionized particles in the flame will cause it to emit sound. (Search YouTube for "singing flame" and you'll find many examples.) This principle was developed into a practical loudspeaker in 1946 by a French inventor, Siegfried Klein, who confined an RF-modulated arc to a small quartz tube, coupled it to a horn, and called the resulting speaker the Ionophone. An intense radio-frequency electrical field ionizes the air between inner and outer electrodes to produce a distinctive, violet-tinged yellow flame in the quartz combustion chamber. When the RF field is modulated by the audio signal, this causes the almost massless ionized flame to expand and contract in what should be a perfectly pistonic manner.

Around the turn of the century, a review of the latest hair-raisingly expensive turntable would often begin with a soothing chant that, yes, the RotorGazmoTron XT-35000 is a tad pricey, but it will be the last piece of analog gear you ever buy—so go ahead, take the plunge. A dozen years later, pressing plants are stamping out LPs 'round the clock, and new high-end turntables are rolling off production lines at a respectable clip. So who knows whether today's Cassandras might be equally premature in bewailing the death of the Compact Disc? Which is to say that I can't in good conscience urge you to pay $12,000 for a CD player on the grounds that the medium's about to die, so splurge now while there's still something to splurge on. But if you have the scratch, and the itch for such a product, step right up and let me tell you about the Krell Cipher.

There are as many ways of designing a digital-to-analog converter as there are engineers. One approach is to select parts from manufacturers' data books and build the product according to the "application notes" provided by the parts manufacturers. This is the electronic equivalent of a paint-by-numbers kit.

A more creative engineer may add a few tricks of his own to the standard brew. Bigger and better regulated power supplies, careful circuit-board layout, tweaky passive components, and attention to detail will likely make this designer's product sound better than the same basic building blocks implemented without this care. Indeed, the vast range of sonic flavors from digital processors containing very nearly the same parts attests to the designer's influence over a digital processor's sound.
