The M Zero utilises simple but sonically effective circuitry using vacuum tube technology rather than
complex techniques using impure semi-conductor type devices, so common in the audio industry.
This kind of circuit architecture is incredibly transparent and revealing. As a natural consequence, part
material plays an important role in the final sonic performance, so we use only the best possible
components and materials. Where components that meet our standards are not available - we make our
The M Zero's circuit arrangement is briefly described below.
All inputs are routed to the line stage via an input selector, volume and balance control. High quality
parts are used throughout the pre amplifier. The circuitry is un-complex and incredibly effective, yielding
a high level of sonic performance.
