Like all its famous predecessors in Nagra range, the HD AMP, uses MOSFET, field effect transistors. They are the closest thing to a valve triode and you can definitely feel its sonic character: direct, fast and musical. The HD AMP has precisely matched clusters of MOSFET, to insure the purest reproduction.
The Nagra HD AMP is fitted with a traditional Nagra Modulometer on the front panel, showing the output power.
