Historical

I have been reading a lot of late. Whether it is due to the reduced appeal of recorded music owing to the ever-decreasing shelves of LPs in our local specialty record store (the owner explains that he still wants to sell LPs; it's the record companies that make it increasingly harder for him to do so with punitive returns policies and deaf ears to back orders), or the fact that it's Spring, I don't know. But the fact remains that I have recently found myself devouring a shelf-full of titles sometimes only vaguely related—horrors!—to high fidelity. Stuart Chase's The Tyranny of Words, for example, first published in 1938 and a finer examination of what came to be called semantics you wouldn't want to find, should be essential reading for anyone involved in writing articles that are still intended to communicate some meaning.

Beginning with this issue, Stereophile readers will notice that more of the subjective equipment reviews are augmented with technical reports describing certain aspects of the component's measured performance. Although test data have lately been increasingly included in reviews, Stereophile has recently made a major commitment to providing readers with relevant measurements of products under review. We have just finished building an audio test laboratory featuring the Audio Precision System One, a sophisticated, computer-based audio test measurement system.

By now you've no doubt realized that Stereophile has changed its size—from 5½" by 8 7/16" to 7½" by 10¼". (All right—maybe you didn't know the exact dimensions of the change, but that's what they are.) We have Edward Chen, Publisher of Stereophile's Chinese edition, to thank for our new size. It is the same size as the Chinese Stereophile and a common size in the Far East. We've been admiring it in Chinese for the last two-and-a-half years, and we thought it would make sense in English as well.

I am reluctant to call any given transistor power amplifier a "best buy" or "breakthrough." From my talks with designers and other audiophiles, it is clear that the state of the art in power amplifiers is about to change. From where I stand, the Adcom GFA-555 is the first sample of this new wave. It is so clearly superior to past amplifiers in the low- to mid-priced range—not to mention most amplifiers two to three times its pric—that I can unhesitatingly recommend it for even the most demanding high end system.

In the introduction to "Recommended Components" in the final issue in Volume One of what was then called The Stereophile, published in May 1966, founder J. Gordon Holt briefly described his Top-Rated Loudspeaker Systems.

Altec A-7
A highly efficient horn-loaded system for use in large to very large listening rooms (at least 15' from the listening area), or for very high-volume "Row-A" listening. Excellent woofer-tweeter blending, moderately deep (useful 45Hz limit in most rooms) and very taut, well-defined low end. Highs smooth and slightly soft, yielding most natural high-end quality at high listening levels. Middles smooth, rather forward, placing closely miked instruments somewhat in front of the system itself.

Considering the amount of careful research, cautious theorizing and wild speculation that have been lavished on the amplifier power question, we should expect to be considerably closer to the answer in 1962 than we were five years ago. This does not seem to be the case.

Publisher's note: The following article, from the early days of Compact Disc, is presented with no claim for absoluteness. (In fact, just as we go to press in the spring of 1986, we received a manuscript from Philip Greenspun, Product Review Editor of Computer Music Journal (Cambridge, MA), who had precisely the opposite result when comparing CD to analog versions of the same recording, though it was unclear that his test procedures were as thorough as in the tests by these authors.) The tests described are neither single- nor double-blind, and the author's decision to forego conversation while listening to the same products does not by any means guarantee lack of mutual influence—especially because their musical tastes are so well known to each other. Moreover, repeating the test with different phono equipment, a different CD player, and a different replica of the master tape would likely yield somewhat different results.

Nevertheless, I think the basic conclusion is sound: good CD reproduction is remarkably close to a fairly good version of master tape sound; there's a good chance that it's more accurate than what you'll get from the average cartridge, tonearm, and turntable.
