The dawning of the age of inexpensive universal DVD-Audio/SACD/CD players may finally be upon us. Cirrus Logic 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 Audio Engineering Society, the main floor of the L.A. Convention Center was transformed into a bazaar of new tools for audio professionals—but the panel discussions upstairs were where the real action took place. On Friday, September 22—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—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 [presumably within a delta-sigma converter negative-feedback loop; see an article on this subject in the forthcoming November issue of Stereophile—Ed.] 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 B&W John Bowers Silver Signature loudspeaker is just such a product, and puts it through its paces to reveal its significant virtues and minor faults.

Most people who now listen to tube amplifiers began with a transistor amp, and know from experience that a tube amp of a given measured power output sounds louder than its nominally identical transistorized equivalent. The unofficial consensus is that you need two to four times the transistor power to achieve the same loudness as you would using tubes. In other words, given the (subjectively) undistorted sound level a 25W (footnote 1) tube amplifier can provide, if you want the same loudness from solid-state technology you would have to replace it with at least a 50W transistor amp (footnote 2).

Choice is good, or so would go the common wisdom. But as John Atkinson points out in "The Crazy You Get from So Much Choice," when applied to diapers and DVD-Audio, choice can quickly develop into a nightmare in which comsumers simply walk away from the shelves, unable to make a decision. Will DVD-Audio suffer such a fate?

We reported last year about the new direction that Bang & Olufsen America has taken in distributing its products: the company has recently opened a series of branded BOA stores around the US. The strategy seems to have paid off. The company reports increased sales of more than 60% in the first quarter of its current fiscal year, and claims that individual shops reported an average sales increase of 20%.

Italian audio journal Fedelta' del Suono (Sound Fidelity) has honored American startup Red Rose Music 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 fête products from new companies.
