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.
Choosing a loudspeaker can be difficult. Although it is easy to be seduced by a certain model's special qualities, that exceptional performance in one area is often at the expense of other important characteristics. Go with high-quality minimonitors for their spectacular soundstaging, but give up bass, dynamics, and the feeling of power that only a large, full-range system can provide. If you choose an electrostatic for its delicious midrange transparency, you may have to forgo dynamics, impact, and the ability to play loudly. Pick a full-range dynamic system for its bass and dynamics, but lose that edge of palpability and realism heard from ribbon transducers.
Triad Speakers has been designing and manufacturing three-piece (woofer and two satellites) loudspeaker systems since 1982. The company was formed that year by designer Larry Pexton and has enjoyed steady growth in their market niche. Their original three-piece loudspeaker was a collaboration with Edward M. Long, of "Time-Align" fame, and Ron Wickersham. It was felt that the ideal loudspeaker would have the least cabinet interference, thus the design decision to keep the woofer separate and the midrange/tweeter enclosure small. Triad speakers were selected for inclusion in the Consumer Electronics Show's Innovations 1990 Design and Engineering Showcase, the sixth time the company's products have been selected for this award.
The VTL 225W DeLuxe monoblocks are very similar to the 300W monoblocks that received such an enthusiastic reception from J. Gordon Holt a year or so ago (in Vol.11 No.10) and, ultimately, most of the audiophile community. Technically, they differ only in output tubes and transformer: the 225W uses EL34s, the 300W uses 6550s. The 225Ws, at $4200/pair, cost $700 less than their more powerful brothers. The question may be raised: Why have two models so close in price and performance? According to David Manley, the 225Ws were built on special order for audiophiles who preferred the sound of EL34s to the 300Ws' 6550s. Demand was so great for the EL34 version that he decided to add it to the line. They look almost identical, the only difference being the smaller output transformer on the 225W and an additional filter capacitor on the 300W's top chassis.
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?
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?"
The whole field of subjective audio reviewinglistening to a piece of equipment to determine its characteristics and worthis predicated on the idea that human perception is not only far more sensitive than measurement devices, but far more important than the numbers generated by "objective" testing. Subjective evaluation of audio equipment, however, is often dismissed as meaningless by the scientific audio community. A frequent objection is the lack of thousands upon thousands of rigidly controlled clinical trials. Consequently, conclusions reached by subjective means are considered unreliable because of the anecdotal nature of listening impressions. The scientific audio community demands rigorous, controlled, blind testing with many trials before any conclusions can be drawn. Furthermore, any claimed abilities to discriminate sonically that are not provable under blind testing conditions are considered products of the listeners' imaginations. Audible differences are said to be real only if their existence can be proved by such "scientific" procedures (footnote 1).
