In the early 1950s, a quiet, undistinguished Senator named Joseph Raymond McCarthy began a crusade against what he imagined were subversive, dangerous elements in American government. His tactics included irresponsible accusation, militant attacks on his opponents, and self-aggrandizing witch-hunting. So virulent were his methods the term "McCarthyism" entered the language. McCarthyism came to mean any unjustified persecution and the false conformity this strategy engendered (footnote 1).

"How sour sweet music is
When time is broke and no proportion kept!"

Editor's Introduction: In 2013, lossy compression is everywhere—without lossy codecs like MP3, Dolby Digital, DTS, A2DP, AAC, apt-X, and Ogg Vorbis, there would be no Web audio services like Spotify or Pandora, no multichannel soundtracks on DVD, no Bluetooth audio, no DAB and HDradio, no Sirius/XM, and no iTunes, to quote the commercial successes and no Napster, MiniDisc, or DCC, to quote the failures. Despite their potential for damage to the music, the convenience and sometimes drastic reduction in audio file size have made lossy codecs ubiquitous in the 21st century. Stereophile covered the development of lossy compression; following is an article from more than two decades ago warning of the sonic dangers.—Editor

A review of the Monitor Audio Studio 20 loudspeaker is a study in contrasts. Compared with most other loudspeakers in the $4500/pair range, this 6.5" two-way from England is a mere pup. Perhaps this observation was sparked by the fact that I'd just finished reviewing the similarly priced Snell Type B, a huge, six-driver, four-way system. The two loudspeakers couldn't be more different, both in physical characteristics and sound.

The Snell Type B is the culmination of three years' research and development effort by designer Kevin Voecks. Along the way, various iterations of the B have been shown at Consumer Electronics Shows. Like other Snell models, the facilities of Canada's National Research Council were used extensively during the B's development, both their anechoic chamber and their double-blind listening techniques.

"In the fields of observation, chance favors only the mind that is prepared."

When Louis Pasteur uttered these words more than a hundred years ago, he must have speculated that they would apply equally well to future circumstances as to the events of his day. What he couldn't anticipate, however, was the technology to which his insight now seems so appropriate.

In hindsight, it was inevitable that two sophisticated digital audio technologies—software-based digital filters and Bitstream D/A converters—were destined to be married in one product. The software-based D/A converters offered by Krell, Wadia, and Theta all used multi-bit ladder DACs, and Bitstream-based units have previously relied on off-the-shelf digital filters.

As I walked through Stereophile's Taipei High-End Hi-Fi show (see the full report next month), I was startled to see four ladies in their 50s carrying Stereophile bags full of brochures. They'd just left a demonstration of Martin-Logan CLSes driven by Aragon electronics and were talking animatedly among themselves as they busily made their way to the next exhibit room. My surprise was repeated throughout the show as I saw an amazingly diverse group of people who had enough interest in high-end audio to get themselves to the Taipei Hilton and pay the show's admission price. Young couples, old couples, entire families, and women were all there to see and hear high-end audio. This was in sharp contrast to the narrow demographic group seen at US and European hi-fi shows: predominantly young to middle-aged males to whom audio is a hobby.
