As We See It

When I attended Britain's Heathrow Penta hi-fi show in September 1987, I had hoped to come back with big news about some breakthrough cartridge or preamp or loudspeaker system. I didn't. No, the talk of the Penta show was something called the "Belt Phenomenon," which may possibly be a breakthrough of some kind, but then again, it may not.

According to a recent newsletter sent to its regular contributors, our "competition"—The Absolute Sound—sees "controversy and confrontation" as the core of its editorial policy. By contrast, Stereophile sees as its modus schtickus an unflagging devotion to, and pursuit of, truth, reason, all of the eternal verities (including some you never heard of), and the intelligent exchange of informed ideas. In honor of all of the above-mentioned precepts (as well as some I didn't mention), this issue of Stereophile is largely devoted to the confrontation between knowledgeable writers for whom the widely proclaimed perfection of the Compact Disc remains a controversial issue.

Almost 30 years ago, Columbia records issued a unique disc called The Art of Jonathan and Darlene Edwards. Darlene sang and Jonathan played piano, and the jacket notes rhapsodized about the depth of feeling they brought to their duos, despite some imperfections of technique.

One of the things that distinguishes a dedicated audiophile from Joe Q. Public is that he has some notion of what audio fidelity is all about.

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.

101 years ago, the tinfoil cylinder started it all. Within 22 years, its heyday was done, and public support swung to favor the then-new wax-mastered disc. 1948 saw the switch to a slower speed and a finer groove, but the flat disc, traced by a stylus, has held sway for almost 80 years now. Even today, people with multi-speed turntables and a couple of arms (or plug-in cartridges) can reproduce from a single phono unit the earliest or the latest discs merely by the flip of two switches (for speed change and cartridge change). All that is about to come to an end.

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.
