Peter Walker (QUAD founder) developed his wonderful ESL57 under the laws of physics and as long as they don't change, all QUAD electrostatics remain current and timeless. Here is an interview with Peter Walker together with the magazine "THE AUDIO AMATEUR"
We have now also developed the Float QA as magnetostatic headphones. You will find detailed information here on our productspage
QUAD Musikwiedergabe, in collaboration with Jürg Jecklin, has further developed these legendary electrostatic headphones. All information on all models of this head speaker can be found on our new website.
„The QUAD electrostatic speaker ESL57 produces such a faithfully real sound that for more than 60 years QUAD has been synonymous with the phrase for the closest approach to the original sound. Together with the ESL63, Peter Walker developed the two very best electrostatics ever.“
