The Audio Research D-115 Mk II amplifier was designed as a pure tube amplifier of the highest quality in Audio Research's golden age in the late 1980's when it was leading the audio vacuum tube renaissance. The engineers proceeded with the design philosophy of utilizing a simple, but proven classic vacuum tube circuit, with none of the Jfet or solid state stages that were used in some of their later designs that get mixed reviews. It has a classic tube sound that is highly stable driving even the most difficult low impedance speaker loads.
