Hempcones and Hemptones

Most manufacturers who advertise in <I>Stereophile</I> hype an exquisite blend of old world craftsmanship and high technology. The gambit is particularly common in the business of selling loudspeakers, where ad copy pushes the sonic advantages of the latest ultra-stiff, indestructible, and nearly weightless cone materials such as Kevlar, carbon-fiber, anodized aluminum, or platinum-plated titanium.

"It costs as much as a car&mdash;and not a used jalopy, either," remarks Michael Fremer. "That's what goes through your head as you contemplate this magnificent $20,190 piece of audio jewelry." The jewelry in question is the <A HREF="http://www.stereophile.com/amplificationreviews/1298jadis">Jadis RC JP80 MC Mk.II preamplifier</A>, which MF compliments for "breathtaking" workmanship and parts quality. He also listens to the thing and reveals what some might consider the most important part: how it sounds.

Album Cover Top 10

There are several easy ways to start arguments among music fans: ask for a list of the most significant albums of all time, or who the greatest songwriters are, or the best bands, or ask which albums sported the all-time greatest covers.

Noise, Modulation, & Digital/Analog Conversion

At the February 1991 Audio Engineering Society Convention in Paris, Audio Precision's Dr. Richard Cabot (see <A HREF="http://www.stereophile.com/interviews/850">my interview</A> in January 1991, Vol.14 No.1) proposed a new technique for measuring noise modulation in D/A converters (footnote 1). The method, based on psychoacoustic principles, attempts to predict the audible performance of D/A converters. Now that <I>Stereophile</I> has added digital-domain signal generation and analysis to our Audio Precision System One, we can employ Dr. Cabot's technique and see if there are any correlations with subjective performance.

Nordost Valhalla interconnect & speaker cable

One of the highlights of any Consumer Electronics Show, I have found, is Nordost Corporation's demonstration of their cables. Using a relatively modest system and non-audiophile source material, they run through a simple, straightforward sequence, climbing up through their product line, culminating with their new, just-introduced model. At each step, the system sounds distinctly better&mdash;clearer, cleaner, with more body and tonal purity&mdash;than with the previous model. There's no hype, artifice, or magic, just a clear demonstration of the progress that Nordost is making as they refine their designs.

ZYX R-1000 Airy S phono cartridge

My wife and I have this ongoing riff: We try to make each other laugh by sharing examples of words we've looked at too quickly and misread&mdash;mistaking <I>offered</I> for <I>overfed</I>, <I>bagel</I> for <I>kegel</I>, that sort of thing. All very subtle and dry and Garrison Keillor. You can hear the belly laughs from there, can't you?

Jadis RC JP80 MC Mk.II preamplifier

"It costs as much as a car&mdash;and not a used jalopy, either." That's what goes through your head as you contemplate this magnificent $20,190 piece of audio jewelry. I don't mean "jewelry" pejoratively; the tubed Jadis RC JP80 MC Mk.II is a gorgeous, gleaming hunk of retro-looking machinery. Two hunks, actually: an equally large remote power supply is connected via an umbilical cord terminated with an elbow connector the size of house plumbing.
