Audio Research D-300
Little is documented about the Audio Research D-300 stereo amplifier. What survives comes from a handful of period references. Audio (January 1995, p.112) reviewed the D300 and noted it was an all-solid-state design. That was somewhat unusual for Audio Research, which was then better known for tube amplifiers. It was priced at $3,995. The same review described its sound as “very fast, live, and dynamic” with an open soundstage, and compared its character to the LS2B Mark II preamplifier. Another Audio article from that issue (January 1995, p.110) grouped the D300 with the company’s AURICLE line of solid-state components, positioning it among leading high-end manufacturers.
Beyond these magazine mentions, no production years, power output ratings, dimensions, or circuit details have been confirmed. The D300 appears to have been a short-lived or low-volume model. No owner’s manuals, service literature, or further reviews are known.
