Quad QC 24 PRE preamplifier Lancaster Grey
Pre-amp
With the QC Twenty Four pre amp, our designer scoured the globe for the very finest components, with possibly the best example of this being the new ‘old stock’ 6111WA double triode.
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 Peter Walker himself stated is, ‘a straight wire with gain’. The QC Twenty Four has 2 main outputs, 2 Tape Play and Record connections and inputs for CD, Tuner, Aux 1, Aux 2 and an optional Phono port.

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.
