Silent Power. Pure Performance.
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.

Engineered Without Compromise
- From its first sketches, the Compact PSU was conceived as a no-compromise solution. Every detail—technical and aesthetic—was considered to ensure optimal performance:
- True linear power supply with custom-made toroidal transformer
- Multi-stage silent filtering for clean, stable energy delivery
- Precision-machined aluminum chassis with resonance control
- Dedicated transformer for Europe or US mains voltage
- Generous 2 A output power
- Optional upgrade with the Nagra Compact VFS for enhanced vibration isolation
This meticulous engineering allows your Nagra system to reveal its full musicality, delivering a more natural, immersive listening experience.
