1936 bis 1950. Before Peter Walker starts to manually coil the first transformers in Huntingdon (which would later become the head office for many decades) he gains initial experience in London’s Sutton Road. On April 2nd 1937 Wireless World reports on the foundation of the company whose facilities would later be bombed out by the German Air Force during the Second World War. The cumbersome move to Huntingdon (90 miles north of London) offers the chance for a new start. The manufacture of transformers earns Peter some money and gives him the freedom to develop better amplifiers for music reproduction.


The Italian Alfa 6C2300 as well as the German Mercedes and the BMW328 impressively show the power with which the aspiring automotive industry starts its rebound.


Parallel to Peter Walker’s first steps Tullio Campagnolo is about to invent bicycle gearing in Italy. Peter and Tullio have in common that both designs endure to this day and form the basis for the latest products of both manufacturers.

1951 bis 1970. Peter Walker’s description of the electrostatic loudspeaker in Wireless World Magazin attracts great attention worldwide. 2 years later, in 1957, half a dozen journalists get a chance to hear the ESL in the London Waldorf Hotel. The QUAD II is still used as an amplifier. Later in 1967 the first 303 / 33 come on the market. Given that in the early 50s the QUAD I (still under the name Acoustical) and a suitable control unit are still in production, those two decades certainly can be referred to as very intense times for QUAD.


While in England people invent music reproduction according to the laws of physics, Belgium, France, Italy, Luxembourg, and the Kingdom of the Netherlands are busy founding the EU. In 1973 the United Kingdom joins the EU as well. Two years after Walker introduced the transistor amplifier, the Americans and Apollo 11 land on the moon.

Automobiles become more elegant and are expressive symbols of an aspiring population. In England Dr. Alex Moulton invents his “small wheel bicycle” which is still being produced almost unmodified to date – just like the ESL57.

1971 bis 1990. In 1981 sound engineers worldwide are introduced to a long-awaited tool: the QUAD ESL63. The development has already started 18 years earlier with the introduction of stereo technology. In the late 80s Peter’s son Ross Walker assumes control for a short period and brings the QUAD 66 on the market whose electronics are just what the times require. For the first time QUAD offers a CD player. For sound studio applications the 510, 520, and 240 Series of professional power amplifiers are manufactured. In Switzerland sound engineer Jrg Jecklin invents the electrostatic headphone called Jecklin Float.


In 1989 “QUAD Musikwiedergabe” is founded in Germany to act as distributor of QUAD products. QUAD Musikwiedergabe also becomes the most important service center for QUAD devices worldwide.


Well-known studios and producers of long-playing records such as Philips in the Netherlands and later on SONY Classics in Hamburg discover the ESL63 as tools of the trade.

1991 bis 2000. In the mid-90s the English company is sold to a Chinese investor. The production tools for the classic electrostatic transducers find their way to Germany where QUAD Musikwiedergabe starts manufacturing the actual transducers as well. Electrostatic transducers and electronics are still produced in China under the QUAD brand. QUAD Musikwiedergabe evolves into a company which specializes in the service and manufacture of the classic QUAD electrostats.  


It’s the time of worldwide changes. Existing economic systems break down and the proven economic systems of the western world gain ground.

Thanks to boundless communication and customers from around the globe small specialized companies start to blossom. Even tiny niche markets can be served worldwide.



2001 bis heute.  By now QUAD Musikwiedergabe has become a contact point for international QUAD friends. In 2005 the company moves into its new house in the Eifel. In 2007 the current versions of the ESL57QA and ESL63QA are introduced. In collaboration with Jrg Jecklin the production of the legendary Jecklin Float is resumed. The 204 QA power amplifier is introduced.


People who bear responsibility live  consciously, enjoy handmade, elaborate products and rediscover proven things.
