With the analogue purist in mind the Twenty Four P has a moving magnet / moving coil toggle switch and direct / variable level control over volumes for use with all kinds of amplification. Unlike the power amplifiers, the Quad pre amplifiers utilise a completely new design. Together with transformers designed by one of the world's leading authorities and relay input switching the musical signal is preserved in its purest form - pursuant to the philosophy of the theoretical perfect amplifier which a Peter Walker himself stated, is 'a straight wire with gain'.
A Truly Iconic Amplifier
Designed by Quad founder Peter Walker, the truly iconic Quad II helped to define the modern concept of high-fidelity sound in the 1950s. Quad has kept the legend alive with the current Quad II classic, a faithful reproduction of the original valve monoblock with build quality and aesthetics lovingly updated for the modern era. The new version takes this a step further, with the development of additional, pre, power and integrated models. (Pictured: Original Quad II Amplifier as designed by Peter Walker).
The Quad II Series circuit design is the work of Tim de Paravicini, a man widely acknowledged to be the UK's foremost valve amp designer. His design is faithful to Peter Walker's Philosophy of cathode loading onto the same output stage and fundamental simplicity of design, ensuring the new amp delivers the same wealth of detail and exquisite tone as its famous predecessor.
