Peter Walker´s description of the electrostatic loudspeaker in Wireless World Magazin attracts great attentions, worldwide. 2 years later, in 1957, half a dozen journalists get the 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 to 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 intensive times for QUAD.

In 1981 sound engineers worldwide are introduced to a long-awaited tool: the QUAD ESL63. The developement has already started 18 years earlier with the introduction of stereo technology. In the late 80`s Peter´s son Ross assumes control for a short period and brings the QUAD 66 line on the market whose electronics are just what the times require. For the first time QUAD offers a CD player. For sound applications the 510, 520 and 240 series of professional power amplifiers are manufactured. In Switzerland sound engineer Jürg 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

In the mid-90`s the English company is sold to a Chinese investor. The production tools for the classic electrostatic transducers find there 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 serviced worldwide.

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 version of the ESL57 QA and ESL63 QA are introduced. In collaboration with Jürg Jecklin the production of the legendary Jecklin FLOAT is resumed. The 204 QA power amplifier is introduced. Followed by a range of other usefull units.People who bear responsibility live consciously, enjoy handmade, elaborate products and rediscover proven things.Well-known studios and producers of long-playing records such as Philips in the Netherlands and later SONY Clasics in Hamburg discover the ESL63 as tools of the trade.ESL57winterFeel invited to be part of what they will describe as Heritage in a cupple of decades.
