"As We See It" in the Stereophile issue dated Summer 1968 (actually published in 1970) noted the idealistic, glowing claims about how four-channel sound could put you right in the concert hail, but urged readers to wait before buying, to see whether quadrisound would indeed bring higher fidelity. We predicted it wouldn't—that whatever the potential of quadrisound (footnote 1), it would not be used to increase fidelity, but rather to play ring-around-the-rosy with music.
An equipment reviewer for one of the consumer hi-fi magazines once confided to a manufacturer that he found it hard to like electrostatics because of the kind of people who usually like electrostatics. His implication—that certain kinds of people gravitate towards certain kinds of sound—is an interesting thought, and one that might bear some further investigation. But there is no questioning the fact that electrostatic speakers in general do have a particular kind of sound, that might be characterized as "polite."
In the last issue we published a rather enthusiastic "Quickie" report on a small, $190/pair speaker system from a new company—the FMI Model 80. It was virtually devoid of low end, even as a stereo pair (pairing effectively doubles bass output), and slightly rough as well as a shade soft at the high end, but it had a quality of "aliveness" to it that almost defied belief. Was it a breakthrough in design? A new transducing principle? No, it was neither. In fact, the Model 80 looks like any one of those hundreds of little bookshelf systems that clutter, the pages of Stereo Review's "Hi-Fi Directory" in tedious profusion.
We're not really sure who coined the term—it is usually attributed to Alistair Cooke, former host of the "Omnibus" TV program—but "audible wallpaper" is an apt term for something that is of more than passing concern for the serious music listener.
A reader who asked to remain anonymous wrote to tell us the results of some tests he saw conducted on one of our top-rated loudspeaker systems. Frequency-response checks showed that the system had virtually no deep bass, a midbass peak, a midrange slump, and a high-end rise. Further checks had shown gross distortion at input levels of over about 6W, and a definitely limited (although adequate for Row-M listening) maximum output-level capability. Said reader then went on to ask how we could possibly consider such a speaker to be one of the best available.
Editor's Note from 1992: This seminal J. Gordon Holt essay on how the art of recording natural sound became compromised in favor of unmusical artificiality for good commercial reasons was originally published in August 1964, in Vol.1 No.8. Though most people these days listen to classical music from CDs, not LPs, in the intervening decades, recording technology has not changed for the better as much as one might have hoped. Nevertheless, the days of wretched multimiking excess described by Gordon are past, and it's rare to find the music treated with the lack of respect typical of a mid-'60s Columbia session. Although some of the smaller companiesReference Recordings, Delos, Chesky, Mapleshade, Dorian, and Sheffield Lab in the US; Meridian, Nimbus, and Hyperion in the UKconsistently use honest, minimal miking, it is not unknown for the majors in the '90s to do likewise. And the use of time delay for spot microphones, pioneered by Denon in the mid-'80s, means that instruments that might tend to become obscured at orchestral climaxes can now be brought up in level without unnaturally time-smearing the sound. I still find it sad, however, that it is rare to hear the sheer dynamic range of a live ensemble successfully captured on a commercial recording.John Atkinson
This is something we don't see too often: an entirely new approach to power amplifier design. As Quad points out in its literature for the 405, class-A operation of transistors provides the lowest distortion, but drastically limits the amount of power an output transistor can deliver without overheating. (Most transistor amps use class-AB output operation, in which each of a pair of power transistors handles part of each signal cycle and shuts down during the other part. Imperfect synchronism between the two halves causes the familiar "crossover distortion," which accounts for most solid-state sound. In class-A operation, each output transistor draws current though the entirety of each signal cycle, eliminating the crossover transition but doubling the amount of time current is drawn, and thus tending to cause the transistor to heat up more.)
The Magnep1anar Tympani I that is the subject of this report is already an obsolete model, having been superseded by the Tympanis IA, II, and III that were unveiled at the CE Show in Chicago this past June. Since many of our readers already own Tympani Is, and dealer stocks of them are being sold at a substantial price reduction, the report should still be of interest. We will publish follow-up reports on the newer models as soon as they become available for testing.
Editor's Note: Although this product has been available for several years, it is being reviewed in considerable detail because it is a strong contender for the title of "Best Available Loudspeaker System, Regardless of Cost," and because we plan to review some of the other contenders for the same title within the next few issues. We feel that since all of these systems represent a considerable outlay of money, prospective buyers should have a thorough understanding of the merits and demerits of each system, so they will know what to expect from them in the way of performyince capabilities and operational requirements.
