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.

• Pure, Linear Power Flow – Hear your music exactly as it was intended, free from distortion or compromise.
• A Transformer with Soul – Custom-built for Nagra, our toroidal transformer delivers power with precision and warmth, giving life to every note.
• Multi-Stage Silent Filtering – Eliminates interference and guarantees a clean, silent energy flow to your components.

Precision-Machined Aluminum Chassis – Provides resonance control and vibration resistance, combining durability with elegance.

Region-Specific Transformer Options – Dedicated versions for European and US mains voltage for optimal performance everywhere.

Generous 2 A Output Power – Plenty of headroom to unleash the full potential of your system.

Optional Compact VFS Upgrade – Add Nagra’s vibration isolation platform for even greater clarity, focus, and musical immersion.

This meticulous engineering allows your Nagra system to reveal its full musicality—unlocking a more natural, lifelike, and immersive listening experience.
