Audio Research D-100 power amplifier
We cannot recall when any new products have generated as much of a stir among perfectionists as the new solid-state equipment from Audio Research. Preceded by rumors of "a new kind of amplifying devicea cross between a tube and a transistor"the announcement of ARC's new power amp and SP-4 preamplifier elicited very mixed reactions from loyal ARC customers, some of whom gleefully anticipated a virtual revolution in audio electronics, others of whom felt betrayed by the company which, having originally convinced them that "Tubes Are Better," suddenly seemed to be doing an about-face and espousing the views of the Enemythe "Soiled-State"forces.
Many years ago, the now-defunct Life magazine ran a feature article about science and its sacred cows, in which a cartoon showed a huge inverted pyramid-shaped structure of great complexity, tapering downward to a single support at its base: a toothpick. The toothpick was labeled "basic premise," the inverted pyramid was the entire body of scientific knowledge.
Everything we do or think or know is based upon assumptions, some of which are rather more justified than others. When we set the alarm clock, we assume there will be a tomorrow. When we reach for the car's brake pedal without glancing at it, we assume it will be where it was yesterday, and that it will stop the car. When we scorn a phono cartridge because it is too bright, we assume the brightness is in the cartridge, not in the rest of our system. We have to trust our toothpicks or live in a world totally devoid of securitya world where 2+2 can equal anything from 3 to 11, all the laws change unannounced every few days, and Greenwich Mean Time is determined by a roulette wheel.
Publisher's Note: For the first time since I've published Stereophile, we are running two completely differentand opposed reports on the same product. Normally, we try to reach some conclusion as to why reviewers come up with opposite views on a product, and resolve the problem prior to publication. In this case, the problem lies in the differing sound systems used for review. Since some readers will have systems like SWW's, and others will have systems more like JGH's, I felt it was valuable to run both reviews.
For the record, SWW's reference system consists of Dayton Wright XG-lO speakers, BEL 1001 amplifiers, a
