Nagra Reference Preamplifier

The Nagra Reference Preamp builds upon the acclaimed HD PREAMP, introducing significant enhancements to analog preamplification. Improvements include custom-made capacitors, next-generation high-voltage power supplies generating 200 V DC grid tension, and increased super-capacitor capacity. Its dual-chassis design separates power supplies for the audio signal and control sections, minimizing interference. Enhanced mechanical damping with a phenolic layer inside the top cover reduces vibrations. These advancements result in a preamplifier that delivers natural, transparent, and three-dimensional sound.
