Quite a time ago the tinkerer and engineer Joachim Kiesler from the small town of Geithain in the south of Leipzig, East Germany, started a revolt for the linear hearing.

His company was an insider tip in the GDR and could as well convince test persons at a fair in Munich when they listened to the sound of different speakers from all over the world while being blindfolded.
