ARC D-350
Almost nothing is documented about the ARC D-350. What little survives comes from classified ads in Audio magazine, which list a unit described as the "AUDIO RESEARCH D 350 AMPLIFIER" (Audio, November 1978, p.149). That suggests the D-350 was a power amplifier made by Audio Research Corporation. No formal literature, specifications or reviews have been located to confirm where it sat in the company's lineup.
A November 1978 classified (Audio, November 1978, p.149) offered a four-month-old example for $1,875, described as flawless. A second ad in February 1979 (Audio, February 1979, p.109) listed the "latest model" at $1,995, noting a saving of $1,000 off an unspecified original price. Beyond these two sale notices, no circuit details, power ratings, dimensions or production years have been found.
