LATEST ADDITIONS

Once again, audiophiles can help themselves and others at the same time by participating in The Cable Company's ninth annual "Summer Against Hunger" campaign. <A HREF="http://Usedcable.com/">The Cable Company</A> and a wide cross-section of its vendors (listed below) have set up a program by which up to 10% of The Cable Company's August sales are donated to <A HREF="http://www.careusa.org/">CARE</A&gt; and the <A HREF="http://www.theirc.org/">International Rescue Committee</A>, with contributions to be used to assist the worldwide disaster relief efforts of those humanitarian organizations.

<A HREF="http://www.mcintoshlabs.com/">McIntosh Laboratory</A> unveiled for the press three new products that they will be showing at CEDIA next month. They are the MX135 A/V Control Center (already shipping), the MVP861 Universal Player, and the MC207 7-channel Power Amplifier, all with McIntosh's signature design and cosmetics.

With the advent of home theater and Internet audio, doomsayers claim that high-end audio's days are numbered. But new high-end audio companies seem to appear at a rapid clip, and vinyl continues to thrive. So is high-end audio gasping for breath or breathing easy?

Until recently, all problems in digital audio systems were blamed on either the analog/digital converters (ADCs) used in mastering or the digital/analog converters (DACs) needed for playback (footnote 1). As the performance of both ADCs and DACs improved, however, a previously unrecognized mechanism for distortion was unmasked: jitter. As we shall see, jitter&mdash;or, more correctly, word-clock jitter&mdash;can be a significant limitation in the technical and sonic performance of digital audio systems (footnote 2).

Recently, we've seen the digital "horsepower" race accelerate with the arrival of digital sources and devices with 24-bit and 96kHz sampling capability. Much of this has been spurred by the 24/96 labels emblazoned on the newer DVD players&mdash;and, within the purer confines of the audio community, by high-end DACs with this same ability. Indeed, it's possible that the <A HREF="http://www.stereophile.com/digitalsourcereviews/259">dCS Elgar</A> DAC, near and dear to John Atkinson's heart and a perennial Class A selection in <I>Stereophile</I>'s "Recommended Components," performs so well with standard 16-bit/44.1kHz sources because its wider digital bandwidth permits greater linearity within the more restricted range of regular CDs.

After two decades of motorcycling, I recently achieved a long-held goal by buying a bike built by Bimota, a tiny Italian manufacturer. Although Bimota engages in a wide range of activities, from two-stroke engine design to racing, they're best known for their exotic, hand-built street bikes. They always include the very best components and feature cutting-edge engineering and performance, but what they're truly revered for is their style. Bimotas unfailingly combine shapes, textures, and finishes into motorcycles that are most often referred to as "works of art."

A move by RealNetworks to cut the umbilical cord between Apple's iPod and the company's iTunes Music Store has raised the ire of some execs in Cupertino. The computer pioneer is threatening legal and technical retaliation against its Seattle rival in the wake of a late July launch of a digital music technology called Harmony that enables the iPod to work with downloads from RealNetworks' music store.
