About the Reference 75
The Audio Research Reference 75 is a balanced hybrid stereo power amplifier from Audio Research's prestigious Reference series, designed for audiophiles seeking top-tier sound quality without excessive power. It features a simple yet refined circuit with JFET input, 6H30 driver tubes, and KT120 (or KT150 in SE variant) output tubes in an ultralinear partially cathode-coupled topology. Praised for its fluid midrange free of hardness, insightful and smooth treble, graceful dynamics, and superior transparency, it excels with conventional speaker loads in non-palatial rooms. The front panel includes twin VU meters showing instantaneous power output, typically low even at high volumes due to efficient transient handling. Rear connectivity includes balanced XLR inputs and screw-down speaker terminals for 4/8-ohm taps. It offers a 12V DC remote turn-on circuit and requires balanced preamp output. The amplifier is no longer manufactured, superseded by models like the Reference 75SE and Reference 80S.
