Our long-awaited laser-audio disc player (usually called the CD, for "Compact Disc") finally arrived, along with a real bonanza of software: two discs—a Polygram classical sampler of material from Decca, Deutsche Grammophon and Philips, and a Japanese CBS recording of Bruckner's 4th Symphony, with Kubelik.
This issue contains a report on a truly ingenious little device called the ABX Comparator, which takes the fraud out of subjective testing. It does this by making its own selection of source A or source B for each listening trial, without telling you which was selected. Only after all the tests will it reveal what you were listening to each time. "Score" sheets are provided so you can list your guesses, compare them with the cold, uncompromising truth, and file the results for posterity. Or better still, for the first hard evidence that has ever been presented that a lot of people can hear differences that cannot as yet be measured.
As of February, 1982, the ownership of this publication passed to other hands. In total despair about its precarious finances, JGH accepted with alacrity an offer by Larry Archibald (an occasional contributor in recent years) to purchase the magazine. This has now come to pass, and it is because of the resulting infusion of money that you are holding this issue in your hot little hands now instead of three months from now (and that is probably being a little optimistic about the way things were).
Editor's Introduction:In 1963, Stereophile's founder J. Gordon Holt published attacks on what he saw as the single largest step backward in high-fidelity sound reproduction at that time: RCA's introduction of "Dynagroove" LP records, where the recorded signal was pre-distorted and dynamically equalized to compensate for the poor performance of cheap phonograph players. "Issue 5...revealed most of RCA Victor's 'revolutionary' new system as nothing more than a sophisticated way of bringing higher fi to record buyers who don't care enough about hi-fi to invest in a decent playback system." Ten years later, Gordon wrote that, "As of 1974, the best we can say for Dynagroove is that there is no audible evidence of it on current RCA releases." (These articles were reprinted in June 1992, Vol.15 No,6, as part of Stereophile's 30th-anniversary celebrations.)—John Atkinson
"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."
The Bose 901 has created more of a stir in audio circles than any other loudspeaker we can think of, with the possible exception of the original Acoustic Research system. Much of the 901's popularity is attributable to Julian Hirsch's rave report in Stereo Review, and there is no doubt but that Amar Bose's compellingly convincing ads had their effect, too. But these things alone could hardly account for the 901's popularity.
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.
Everyone knows that advertising people make more money than ordinary people, but many assume that the high pay is because ad writing is so difficult. This is not true. Low-income people can write advertisements, too, so just in case somebody should accost you on the street and ask you to write an advertisement, here is how you may go about it.
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 companies—Reference Recordings, Delos, Chesky, Mapleshade, Dorian, and Sheffield Lab in the US; Meridian, Nimbus, and Hyperion in the UK—consistently 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.)
Hey, kids, here's the Big News. We've been deluding ourselves all along, worrying about piddling little bits of distortion that we can't hear at all. How's your preamp distortion? 1% at 1 volt out? You have a perfect preamp—a veritable straight wire with gain! That ear-shattering shrillness is all in your mind, because it has now been demonstrated that the human ear cannot perceive distortion levels of less than 6–12% on "normally complex music." If you think you can hear 0.1%, you are deluding yourself.
