The loudspeaker coming under the microscope this month emanates from north of the border. The Canadian loudspeaker industry has benefited enormously in the last few years from having the measurement, testing, and listening facilities of Canada's National Research Council in Ottawa made available to it on a commercial basis. Unlike the US or even the UK, where a new speaker designer has pretty much to rely on his own resources, having to invent his own test procedure as well as design the product, the Canadian equivalent can have his loudspeaker tested under standard conditions, quickly indicating whether he is on the right track or not. (He still, of course, has to rely on his own talent to get on the right track in the first place or to get back on it if it appears that something is amiss.)
The arrival of the Mark Levinson No.30 digital processor more than 2½ years ago marked a turning point in digital-audio reproduction. Although the No.30's $13,950 price tag put it out of reach of all but a few audiophiles, its stunning performance suggested that much more musical information was encoded on our CDs, waiting to be recovered by better digital processors. Further, it was inevitable that this level of performance would become less expensive over time. I was more excited by the No.30 than I've been over any other audio product. In fact, its musical performance was so spectacular that it alone occupied the Class A category in Stereophile's "Recommended Components."
Over the past two and a half years, I've auditioned and reviewed a number of digital audio products. It has been a fascinating experience both to watch digital playback technology evolve and to listen to the results of various design philosophies. The road to more musical digital audio has been a slow and steady climb, with occasional jumps forward made possible by new techniques and technologies. Making this odyssey even more interesting (and confounding), digital processors seem to offer varying interpretations of the music rather than striving toward a common ideal of presenting what's on the disc without editorial interjection.
As an equipment reviewer, I find it helpful to talk to audiophiles and music lovers about their systems and upgrade plans. Fortunately, Stereophile's computer supplier and troubleshooter, Michael Mandel, also happens to be an avid audiophile. I say "fortunately" because I rarely get a chance to talk to people who put down their hard-earned money for hi-fi components. Instead, I usually converse with equipment designers, technicians, and marketing types, hardly people who reflect the buying public. It is thus a valuable education to get feedback from real-world consumers to find out what kind of products they want, their priorities, and how much they're willing to spend for certain levels of performance. They have a view distinctly different from that of the often jaded reviewer who is used to enjoying the best (albeit temporarily) without agonizing over its cost.
During an Audio Engineering Society meeting where a former colleague of mine was giving an arcane technical discussion of the optical considerations of data retrieval from a Compact Disc, a longtime AES member whispered to me: "What happened to the good old days of AES meetings when we talked about things like tape bias and saturation?"
Whenever anyone marvels at the enormous Genesis II.5 loudspeakers in my house, I'm quick to tell them that the II.5 is the smallest, least expensive loudspeaker made by Genesis Technologies. In fact, the company makes two larger speaker systems, the $33,000 Genesis II and the $70,000 Genesis I (footnote 1).
Doug Sax is undoubtedly one of the most controversial and outspoken figures in audio. As co-founder, with Lincoln Mayorga, of Sheffield Lab, Doug pioneered the first modern direct-to-disc recording. His perfectionist methods may be controversial, but the results certainly are not: Sheffield Lab recordings are nearly universally praised by the audiophile community, while the Billboard Hot 100 always features at least one Sax-cut disc.
I find it more than a little ironic that in 1990 the only two digital-to-analog converters to employ a new state-of-the-art DAC also use vacuum tubes. Many in the audio community consider tubes an anachronism, and find it surprising and humorous that they are still used in newly designed audio products. The fact remains, however, that these two tubed digital processors achieve the best digital playback currently availableand by a wide margin. Moreover, their respective designers' technical savvy and passion for building leading-edge products is reflected in their choice of these superlative and very expensive new DACs. Is it mere coincidence that both designers also chose vacuum tubes to realize their vision of no-compromise digital playback?
