The QUAD electrostatic speaker ESL produces such a faithfully real sound that for 50 years QUAD has been synonymous with the phrase For the Closest Approach of the Original Sound: Together with the later ESL63, Peter Walker developed the two very best electrostatics ever.

When QUAD decided in 1996 to terminate the production of its initial model ESL57, QUAD Musikwiedergabe (their German representative at that time) took over the necessary tools to Germany. First they started manufacturing the major spare parts for this speaker, but soon the production was extended to virtually all parts of QUAD ESLs which are not anymore in production in the UK:

Today QUAD Musikwiedergabe not only is in the position to repair or to refurbish any QUAD ESL but they deliver both original ESL`s and all the contemporary QUAD equipment, worldwide.

In addition there is a ESL design variant from BRAUN, Germany. QUAD Musikwiedergabe produces all the parts for this speaker too.
