The dawning of the age of inexpensive universal DVD-Audio/SACD/CD players may finally be upon us. <A HREF="http://www.cirruslogic.com/">Cirrus Logic</A> recently announced the introduction of their CS4392 integrated circuit chip, which the company describes as a high-performance Crystal digital/analog converter that "delivers unrivaled sound quality while providing manufacturers a cost-effective solution for next-generation DVD-based audio products including DVD-Audio and Super Audio CD (SACD) players."

For the 109th convention of the <A HREF="http://www.aes.org/">Audio Engineering Society</A>, the main floor of the L.A. Convention Center was transformed into a bazaar of new tools for audio professionals&mdash;but the panel discussions upstairs were where the real action took place. On Friday, September 22&mdash;just an hour before researchers Dr. Stanley Lipshitz and John Vanderkooy of Ontario's University of Waterloo presented a paper offering a mathematical proof for the "imperfectability" of one-bit delta-sigma recording systems&mdash;Sony Corporation issued a clarification of the technical standards for its Direct Stream Digital technology, the basis of the Super Audio Compact Disc. DSD, it now appears, is a one-bit technique as it applies to consumer playback systems, but uses a multi-bit PCM quantizer [<I>presumably within a delta-sigma converter negative-feedback loop; see an article on this subject in the forthcoming November issue of </I>Stereophile<I>&mdash;Ed.</I>] at the recording and mastering ends of the business. (The Lipshitz/Vanderkooy paper is available as AES preprint #5188.)

Citing the potential danger of "collective dominance" of the music business, European Commission members have nixed the proposed merger of American media conglomerate Time Warner and British music-industry powerhouse EMI. The $20 billion joint venture may still have some small chance at a future, provided the companies make further concessions to allay fears of monopolistic control of music prices in Europe.

Every once in a while, John Atkinson comes across a speaker that redefines the boundaries of what is possible with the moving-coil loudspeaker approach established 60 years ago by Rice and Kellogg. JA feels that the <A HREF="http://www.stereophile.com//loudspeakerreviews/272/">B&W John Bowers Silver Signature loudspeaker</A> is just such a product, and puts it through its paces to reveal its significant virtues and minor faults.

This smallish loudspeaker system has been getting high ratings in the English audio magazines for some years but was not available to US consumers until recently, when the small firm (literally a Mom'n'Pop enterprise, footnote 1) arranged for US distribution through Audio International.

The Spendor BC-1 is about as unimpressive-looking as any other smallish three-way loudspeaker, of which there are countless hundreds of models being made in the US at present. In fact, we were so ho-hummed by the mundane appearance of this speaker that we found it hard to connect the pair up and give them a listen.

In general, it's still true that you get what you pay for. But sometimes you don't . . . you get more. What audio product has surprised you with its return on investment?

Italian audio journal <I>Fedelta' del Suono</I> (Sound Fidelity) has honored American startup <A HREF="http://www.redrosemusic.com/">Red Rose Music</A> with "Product of the Year" awards for the company's Model 3 preamplifier and Model 2 power amp. The award is especially noteworthy in view of the fact that the monthly publication, based in Terni, Italy, does not normally f&#234;te products from new companies.
