5 Quad products have always been amongst the finest audio products in the world. When P eter W alker started making commercial P A systems in 1936, few could have predicted the revolution in hi-fi that many of his products were to cause, the longevity they would have and the esteem with which they would be held. In the early 1950s, he and Gilbert B ...

8 P eter W alker always believed that an amplifier should be as simple as possible - engineer with the fewest possible components and with a performance largely independent of those components. The QC-twenty-four , a low-noise RIAA curve phono stage has an understated elegant simplicity , although we use high quality components wherever these appea ...

F or the analogue purist, the combination of a good valve amplifier and a good turntable is the closest possible approach to the original recording. There are two options for adding such functionality to our valve pre-amplifiers. A solid-state module is available for the standard QC- twenty-four pre-amplifier (known as the QC-24 phono stage) which ...
