What HFL Thinks
Nagra Compact PSU – In 1951, Stefan Kudelski, a gifted 22-year-old engineer, developed an extremely high quality, miniature, self-contained audio recorder which he named simply the “Nagra I”. Nagra is a Polish word meaning “will record”. The interest in his invention was immediate. The Nagra II and III followed in the mid to late ‘50s revolutionizing the world of radio broadcasting, cinema and music. Nagra even made it to space with the Apollo mission.

At Nagra, we know that exceptional sound begins with exceptional power. For decades, our legendary recorders set the standard thanks to their silent, high-performance power supplies, delivering unmatched reliability and autonomy. Carrying this heritage into the Hi-Fi world, we designed external power supplies for our HD and Reference lines that pushed the boundaries of sonic purity.
