Products > Amp Audio Upgrade Kits > Quad Amplifiers

Our audio upgrade kits offer a selection of the best quality modern production items along with high quality new old stock valves to give you a an improved sound and a cost effective upgrade. We have over 30 years’ experience with using and listening to high end audio amplifiers and over 25 years in improving the valves. These kits have been put together after many hours of listening tests to confirm the valves performance in any given application.

Since Peter Walker founded Quad in 1936, all Quad products have displayed originality in design and outstanding audio excellence. A world leader in audio amplifier and electrostatic speaker design, Quad has been recognised by awards from around the world including the Queen's Award for Technological Achievement in 1978 the only one ever presented to an audio hi-fi equipment manufacturer. It is hard to believe that the legendary Quad 11 was discontinued in 1970, yet my own Quad 11 still outperforms many high end amplifies some 45 years on. Our kits use the best current production and NOS valves to help you get the best sound out of these legendary amplifiers.
