Description ▴

The Nagra HD AMP was designed for ultimate high-end systems that are able to reproduce music with the utmost fidelity. The HD AMP consists of mono amplifiers capable of driving the most demanding speakers and transcending their performance. The HD AMP came from the need of bringing Nagra’s signature transparency to more powerful amplifiers so as to accommodate even larger rooms and less sensitive speakers
