With the M 40 HV, the high-res players and preamplifiers of the HV series have a unique and uncompromising power amplifier available, which meets the highest audiophile requirements under a wide range of operating conditions. Of course, it is also the perfect amplifier for any other high-end chain. In our 40-year history, we have learned that there is not one perfect solution for all requirements in electroacoustics, but that every concept has its strengths and weaknesses. We have consistently developed the optimal solution for each requirement, be it tube technology or the latest digital signal processing.
We have given our best power amplifier a circuit concept that is unique in the world and combines classic analog technology, tube technology, high voltage amplifiers and intelligent parameter control. The entire input amplification takes place with the help of selected high-end tubes of the type 6SN7. They work in Class A mode, which results in a very harmonious sound and the musical and tonal advantages of tube technology are reflected in the sound character of the M 40 HV.
The input stage is designed as a symmetrical differential amplifier in full tube cascode circuit. The following voltage amplifier stage is a high voltage (HV) J-FET amplifier stage with triode characteristics and characteristic, which also works in a pure Class A range.
