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.

Audio Research D76A Amplifiers user reviews : 4.6 out of 5 ...
http://www.audioreview.com/product/amplification/amplifiers/audio-research/d76a.html
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.

Many audiophiles have said that the D-79 is the best amplifier that ARC ever built. With a massive power supply for its modest 75 watts per channel, the D-79 draws 750 watts from the AC line at full output. This amplifier uses a matched pair of 6550 output tubes per side with an additional 6550 as a voltage regulator.
