AUDIO RESEARCH D75A STEREO TUBE AMPLIFIER | 75 watts RMS. Very clean vintage ARC D75A with gold faceplate. For many years I collected ARC amps of this vintage. I have a sweet spot for that wonderful liquid Audio Research sound found in the 1970's to early 1980's amps like the D75A, D76A, D79 (A,B,C), D90B and D150.

The mids are pure tube- elegant, rich and liquid with just a hint of that "romantic sound" that I hear some reviewers talk about old tube gear having. The top end is clean, with just a hint of fuzz (this was reduced with new output tubes, and re biasing, but is a symptom of the design). Weakness: Heat and weight.

However,I was disappointed with the sound, the owner sold the preamp so he has the amp connected with a ipot ...
