The M 40 HV Mono Power Amplifier provides the HV-series High-Res players and pre-amplifiers with a unique and uncompromising power amplification solution that meets the most extreme audiophile demands across a vast range of operating conditions. This exceptional device can also serve as the perfect power amplifier for any other High-End set of equipment. Through our forty-year history, we have learned that the world of electro-acoustics does not allow for a single perfect solution to meet all requirements. Instead, every design philosophy comes with its own set of strengths and weaknesses. As a result, we have developed optimal solutions to cater to each specific need, whether it involves valve technology or the latest advancements in digital signal processing.

The M 40 HV leverages our extensive experience in various domains of High-End audio technology. It incorporates audiophile valve construction for the input stages and High Voltage technology for the transistor stages. Additionally, it features intelligent thermal processor control for the output stages, all encased within our usual uncompromising design and construction.
