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.
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.
Editor's Note: Those of us who cut our engineering teeth on tubes still remember the advent of the solid-state amplifier with mixed feelings. Yes, they were lighter and cheaper per watt than the thermionic hulks we loved so much, but they broke all the time (thanks to the germanium transistor) and sounded like—well, let J. Gordon Holt tell us what they sounded like in an "As We See It" article from Vol.1 No.10, first published in May 1965. We also develop the theme with a JGH review of an early transistorized amp, as well as a selection of readers' letters from the early days of Stereophile. Enjoy.—John Atkinson
In 1960 the high-fidelity field was in a period of stasis. The hi-fi boom was starting to crest out, and there were three magazines for audiophiles: High Fidelity, Stereo Review and Audio. The first two were (and still are) little more than vehicles for their advertising, more dedicated to promoting their advertisers' wares than in advancing the state of the art. Audio was more into equipment testing than either of the mass-hi-fi magazines, but it too was contributing to the stagnation by listening to its test results rather than to the components.
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.
