The Quad II Classic Mono

This is a faithful reproduction of the original mono amplifier – 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.
