Is it possible to make a $700 "mainstream-audio" power amplifier sound exactly like a high-priced perfectionist amplifier? Bob Carver, of Carver Corporation, seemed to think he could, so we challenged him to prove it.

About 2200 years ago, a Greek writer named Antipater of Sidon compiled a list of the seven wonders of the world, which included a 100'-high statue of the Sun god Helios, erected next to the harbor of Rhodes on the Aegean sea. A of S called it the Colossus of Rhodes, for an obvious reason. Now there's a new Colossus, the derivation of whose name is a little less obvious, but which could justifiably be included in any contemporary listing of the seven wonders of the audio world.

A persistent complaint from some of our readers concerns our seeming preoccupation with exotic components. (Presumably what they mean are scarce, unusual, or hard-to-find components, because "exotic" really means "from a foreign country," and there is sure as hell nothing hard-to-find about a Panasonic receiver.) "Why," you ask, "do you devote so much space to reports on components we can't buy from our local audio discounter? Why can't we have more reports about products from the old, established, reliable companies like KLH, Harman/Kardon, Electro-Voice and Sansui, whose stuff we can listen to at a local dealer before we commit our hard-earned dollars to a purchase?" One subscriber even cancelled his subscription because of this, claiming that the unavailability of the products we review makes our reports "irrelevant." Well, he had a point, but not a very good one.

Editor's Note: In 1985 and 1986, an argumentative thread ran through Stereophile's pages, discussing the benefits or lack of double-blind testing methods in audio component reviewing, triggered by J. Gordon Holt's review of the ABX Comparator. As this debate is still raging nearly 15 years later, we present here the entire discussion that bounced back and forth between the magazine's "Letters" section and features articles. It was kicked off by a letter from C.J. Huss that appeared in Vol.8 No.5.—John Atkinson

Question: What is it that almost every audiophile takes for granted, yet has more effect on the sound of his system than does any single component in that system? Answer: His listening room.

Well, it's that time. The time of reckoning, the moment of truth. It's renewal time.

Most of you have noticed the hyphenated numbers on your address labels, and most of you guessed what they were: Expiration codes. If your label has a 1-12 number on it (or no hyphenated code at all), the next issue of The Stereophile, Issue Number 12 [published in September 1966—Ed.], will be the last one that will arrive on your present subscription.

The main inherent advantage of the full-range electrostatic loud speaker system is that it allows a single diaphragm to embody the conflicting attributes needed for optimal performance at both extremes of the audio range. Its thin-membrane diaphragm can be made exceedingly light, for superb transient response and extended HF response, yet it can be about as large in area as desired, for extended LF response.
