LATEST ADDITIONS

I suppose that most high-end designers dream about making a Statement Product&mdash;their best effort, without regard for price. <A HREF="http://www.stereophile.com/interviews/767">Victor Khomenko</A>, majordomo of Balanced Audio Technology, got the bug and came up with the VK-50SE. This <I>hugely</I> full-functioned line-stage preamp derives its Special Edition (SE) moniker from the eight hot-running, super-hush-hush Russian 6H30 Reflector SuperTubes that populate the circuit board.

Pass Laboratories' X amplifier series represents the efforts of designer Nelson Pass to prove that simple linear amplifier topologies can be scaled to provide high-quality audio performance at <I>very</I> high power levels. The handsome X1000 monoblock under scrutiny here, the largest and most powerful amp in the Pass stable, makes 1000W into 8 ohms and a mighty 2000W into 4 ohms. The amplifier has no global negative feedback, and only two gain stages: the front-end provides all the voltage gain and feeds a high-current follower stage.

Clear Channel Communications, Inc. has settled the first of what could be a long string of lawsuits over its purportedly monopolistic marketing tactics.

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.

The Vinyl Record Day website recently ran a poll to determine the top ten album covers of all time. What is your pick for the single greatest cover, whether it be for an LP, CD, or high-rez audio disc?

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.
