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. The Compact PSU proudly continues this tradition—delivering reference-grade performance in a refined, space-efficient design.

From the very first sketch, the Compact PSU was imagined as more than a power supply — it was designed as the silent foundation of your musical journey. Every element, inside and out, was crafted to deliver not just performance, but an experience.
