Audio Research D-1004 (circa 1979)
Almost nothing is documented about the Audio Research D-1004. What little survives comes from a handful of classified ads in Audio magazine in early 1979. One seller listed a mint-condition D-1004 at $895 (Audio, February 1979, p.109). Another ad in the same venue from March 1979 repeated that price (Audio, March 1979, p.127). No other information was found. Whether it was a power amplifier, a preamplifier, or some other type of component is not recorded. The $895 price would have put it in the company's upper-midrange tier at the time. That is well below the D-350, offered in that same ad column for $1,995 (Audio, February 1979, p.109), but far above entry-level models.
No design details, specifications, or production figures have been found. The D-1004 may have been a short-run product, a dealer-ordered variant, or a model that was advertised but never formally cataloged. Until an owner's manual, a schematic, or a contemporary review surfaces, it is confirmed by marketplace evidence and nothing else.
