Founded on Stefan Kudelski’s 1951 breakthrough—the portable “Nagra I” recorder—Nagra became synonymous with Swiss precision in sound, earning Academy Awards® (1978, 1991) and global acclaim in broadcast, cinema, and music. Since 2012, Audio Technology Switzerland SA has carried the legacy forward under Kudelski family ownership, operating across high-end hi-fi, professional recorders, and select security/law-enforcement devices. Iconic innovations range from the Nagra III and IV-S portables and the Apollo-flown SN, to the D 96 kHz/24-bit digital recorders, PL-P and VPA tube electronics, VI multitrack, HD PREAMP, and the 2022 Reference Turntable. Today, Nagra serves discerning listeners and professionals who demand reference-grade fidelity, enduring engineering, and timeless design.
