I must admit that even before I connected up this amplifier I was put off by the accompanying literature. B&K makes some persuasive points about the validity (or rather the lack thereof) of some traditional amplifier tests, but the literature was so loaded with flagrant grammaticides, syntactical ineptitudes, and outright errors that I could not help but wonder if the same lack of concern had gone into the product itself (eg, the term "infrasonic" is used throughout to mean "ultrasonic"). Good copy editors aren't that hard to find; B&K should have found one.
These diminutive little sleepers have been available in the US for quite some time but have attracted little attention because (1) they have never really been promoted and (2) they are just too small to look as if they could be worth $430 a pair.
Several issues back, we reviewed rather enthusiastically a pre-production prototype of this preamp. The original was an unprepossessing-looking device on two chassis, interconnected by a 3' umbilical, with a squat little preamp box and an even squatter power supply with humongous cans sticking out the top. We averred that it sounded nice. The production model is so nicely styled and functionally smooth that we wondered if it might not be another Japanese product. 'T'ain't.
Bill Firebaugh's first product, the outrageous-looking Well-Tempered (tone) Arm, established him as one of audio's most innovative designers. At the 1985 Winter CES, he showed a prototype companion product—the Well-Tempered Turntable—and was producing production units by January 1987. He discusses here the WTT's unusual design features. (Readers should note that, since we have not yet tested the new turntable, this interview is not to be interpreted as an endorsement of the product.)
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.
To high-end audiophiles, the Boulder 500 amplifier and its less expensive derivative, the 500AE (Audiophile Edition), would not seem to be "high-end" designs. They are designed around op-amps (felt by many to be generally poor-sounding), they have scads of negative feedback (which is perhaps why op-amps sound bad), and they have only a moderately hefty power supply. Why, then, is Stereophile publishing a review of an op-amp–based power amplifier? Read on...
"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.
Everyone knows music is a good thing. More than merely good, it appears to meet some kind of human need, because every race in every land has a musical tradition going back to before recorded or recounted history. Some of their music may not seem like music to our unsophisticated ears, but as soon as someone discovered that two sticks of different sizes produced different pitches when struck on a venerated ancestor's skull, he advanced beyond mere rhythm to what must be considered music. (Two sticks would, presumably, play binary music: the first precursor of digital sound.) In fact, were there no music at all today, humankind would probably find it necessary to invent it on the spot, along with a mythology relating how it was created on the eighth day, after ingrown toenails.
If you are to believe all the promotions for the Compact Disc, simply buying a player will transport you instantly to sonic nirvana. No background noise! No distortion! Flat frequency response from 20 Hz to 20kHz, pIus or minus zilch! The most perfect sound that modern hightech can provide! But if CD sound is so perfect, what are so many people screaming bloody murder about? It seems that half the golden ears who hear it are smitten with hate at first hearing. The other half finds it the best thing since tax shelters.
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).
There was a time, very recently in terms of human history, when high fidelity promised to free the music lover from the constraints of the concert hall and the local repertoire, allowing him to choose at his whim any orchestra in the world playing any work he desired under the baton of any conductor he preferred. "All the pleasure of concert-hall listening, in the comfort of your home," was the way one display advertisement painted this musical utopia which, only 20 years ago, seemed right around the corner.
Ever since Stereophile took up the cudgels for subjectivity, and had the temerity to insist that even the best products have certain colorations, we have stressed compatibility in choosing components. By compatibility we do not mean merely matching impedances and signal levels, but mating components whose sonic peculiarities tended to offset one another.
It says something for the state of technology that, after a quarter of a century, there still is no authoritative explanation for why so many high-end audiophiles prefer tubes. Tubes not only refuse to die, they seem to be Coming back. The number of US and British firms making high-end tube equipment is growing steadily, and an increasing number of comparatively low-priced units are becoming available. There is a large market in renovated or used tube equipmentI must confess to owning a converted McIntosh MR-71 tunerand there are even some indications that tube manufacturers are improving their reliability, although getting good tubes remains a problem.
Many audiophiles who have only recently subscribed to Stereophile will be surprised to find that those clunky, heat-producing, short-lived tubes that reigned up through the mid-'60s are still Executive Monarchs in the mid-'80s. Why, for Heaven's sake? Because, despite everything, people like them.
Whenever an audio high-ender thinks about tubes, he usually thinks about Audio Research. This is only natural, because Audio Research Corporation was almost single-handedly responsible for saving tubes from oblivion in the early '70s when everyone else switched to solid-state. But ARC was soon joined in its heroic endeavor by an upstart company called Conrad-Johnson, which entered the fray in 1977 with its PV-1 preamp, priced at an affordable (even then) $500.
