Musical Fidelity X-24K D/A processor

The standalone digital/analog converter emerged as a product category in 1987 with the appearance of the Arcam Black Box and the Marantz CDA-94, closely followed by the PS Audio Link. The idea was that putting the sensitive D/A-conversion and analog stages in a separate enclosure with its own power supply would maximize the sound quality when compared with packing these circuits in the same box as the transport. However, it turned out that the routing of the digital data between transport and processor in the form of an S/PDIF- or AES/EBU-encoded bitstream could introduce word-clock jitterwhich undid much of the sonic advantages. (See "Bits is Bits" by Malcolm Hawksford and Chris Dunn, <I>Stereophile</I>, March 1996.)

Fine Tunes #8

Bill Gates would have you believe we live in a plug'n'play world. Apple has proselytized same since day one. But I'm here to tell you it just isn't so for high-end audio. The orientation of a component's AC plug—even the quality of the wall receptacle itself—affects the sound! Oh no, Mr. Bill, not something else to futz with! Will it never end?

IBM, NARAS Join Forces on Grammy Website

The official <A HREF="http://www.grammy.com/">website</A&gt; of the 41st Annual Grammy Awards was launched earlier this month with the help of a media team from the Atlanta division of <A HREF="http://www.ibm.com/">International Business Machines</A>. The Java-based site provides background information on the artists and events of the music-awards extravaganza, taking place Wednesday evening, February 24, at the Shrine Auditorium in Los Angeles.

Exploring Audio's "Last Frontier"

Two elements that keep the audio business interesting are the new companies and technologies arriving almost every week (see also BW's <A HREF="http://www.stereophile.com/news/10382/">story</A&gt;). Some stick around for years, while others fade away between hi-fi shows. But amid the incessant change are a handful of characters who stay with it, continually evolving with the industry and reinventing themselves with each twist and turn.

Kimber Offshoot DiAural Promises Loudspeaker Renaissance

In the classic textbook example, the Doppler effect is demonstrated by an increase in both pitch and volume (or amplitude) of a train's whistle as it approaches a station, followed by a decrease in pitch and volume as it moves away. This effect---the shift of a frequency emitted by a moving object---leads to a fundamental flaw in audio technology. A midrange driver behaves like the approaching-and-departing train when it attempts to reproduce varying frequencies. When the driver is fed simultaneous 400Hz and 2kHz tones, the forward movement of the cone at the lower rate modulates the 2kHz tone upward in pitch and amplitude; when it moves backward it modulates the higher tone downward. (The human eardrum also behaves this way, but the brain's audio-analysis circuitry knows how to deal with it.)

Internet Radio Listening Doubles

A study released earlier this month by <A HREF="http://www.arbitron.com">The Arbitron Company</A> and <A HREF="http://www.edisonresearch.com">Edison Media Research</A> shows that Internet radio broadcasting continues to be a fast-growing medium. The survey of Arbitron diarykeepers also brings to light both the challenges and opportunities that the Internet presents to radio broadcasters, particularly in the much-talked-about arena of e-commerce.

The Miracle Makers Debuts at Steinway Hall

Rare violin dealer Geoffrey Fushi has devoted many of the past several years and a substantial portion of his liquid assets to producing <A HREF="http://www.beinfushi.com/miracle.html"><I>The Miracle Makers</I></A>, a reference book-and-recording project honoring the works of Antonio Stradivari and Giuseppe Guarneri del Gesu, late 17th- and early 18th-century makers of the world's most sought-after violins. Fushi is also the founder of the <A HREF="http://www.stradivarisociety.com/index.html">Stradivari Society</A>, a philanthropical organization of violin fanciers who loan their invaluable instruments to gifted students. Members believe that their treasures were intended to make music, not merely to gather dust in heavily guarded vaults.
