Quad QII CLASSIC MONO POWER AMP Lancaster Grey
QII-Classic
Integrated Amplifier
This is a faithful reproduction of the original – the new Quad II Classic offers audiophiles the chance to recreate the spirit and atmosphere produced by one of the most famous amplifiers in audio history. Peter’s circuit, notably the design of the output transformer has become of legendary status – analysed by the finest minds in the industry.
The Quad II classic has been recreated accurately with output valves and input valves the equivalent of those used in the original. The output valves produce around 15W per channel operating in Class A, which allow a gloriously sweet and refined sound with appropriately matched contemporary loudspeakers.

About brand
Quad
The history of Quad is one of technical achievement in the field of sound reproduction. It is a story that began with the Quad 1 amplifier, which brought the benefits of 15 years knowledge and experience in professional audio and industrial products to the task of making the most accurate domestic audio amplifier of its age.A few years later, in 1953, the product which set the standard for amplifiers was the Quad II Power Amplifier, the time of Queen Elizabeth’s Coronation and the year in which Mount Everest was finally conquered. This amplifier pioneered the principle of cathode coupling through the output transformer to reduce harmonic distortion to almost negligible levels. Such was its clear superiority that this model remained in production for 18 years. Three years later, in 1956, Quad demonstrated the first true full-range electrostatic loudspeaker. This remarkable product (known later as the ESL 57) used a virtually mass-less plastic film as a moving diaphragm between two charged plates. Compared with moving coil loudspeakers, the ESL 57 was free of unwanted colourations and distortions. This landmark product remained in production, virtually unchanged, for 28 years.
