NAD C375BEE graphite

The C 375 BEE adopts many of the improvements and refinements found in the famous M3 amplifier from the Masters series. For example, it features the distortion suppression circuit and BEE Clamp power supply, systems invented by Bjorn Erik Edvardsen, head of advanced studies at NAD. The tone controls benefit from the latest enhancements, and the signal path design on the circuits has been carefully engineered to reduce distortion and noise to remarkably low levels. To deliver the enormous supply currents to the output stages, large copper traces have been installed.
