Kirksaeter - genauer "Audioson Kirksaeter" bzw. "Audioson Per Kirksaeter", Erwin-Rommel-Strasse 4, 40470 Düsseldorf.
Deutsche Importfirma der in Handarbeit hergestellten hochwertigen HiFi-Geräte und Lautsprecher.

"KIRKSAETER are European, handmade products of outstanding quality and reliability. For more than 45 years KIRKSAETER has stood for innovative, progressive Audio constructions. They are the world's first produced transistorized amplifier using complementary output transistors, and the first not to use a bass reducing protection condenser in the output. Per Kirksaeter was the first to use symmetric voltage supply and modular technology; the first to make a FM-tuner with the incredible sensitivity of 0.4 µV; probably also the first one to construct a small compact monitor speaker with full bass response. By these, he gave the innovation standard for the Audio and High End industry to come. Patents and Awards prove this.
His company AUDIOSON was a cofounder of The German High Fidelity institute that in the early sixties worked out the base for the later international standard DIN 45500."
