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.
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.
Now that Sony has bought CBS's records division, and the infamous Copycode bill seems to be dying in Congress, the way may be clearing at last for the US introduction of the new Digital Audio Tape system. This has sparked renewed speculation in the industry about the impact DAT will have on existing formats, particularly the fledgling CD. Some are convinced DAT will kill CD, because of its ability to record as well as play digital recordings. Others believe DAT won't even gain a foothold in the market, for the same reason quadraphonic sound laid an egg back in the '70s: The public can't handle more than one "standard" format. I feel that both views are wrong, and thatas is usually the case with extreme viewsthe truth lies in between. I believe DAT will catch on in the marketplace, but never in a big way, and certainly not the way CD has. Here's why.
