Technical overview
The M2 Line Balanced 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
own.
The M2 Line Balanced's circuit arrangement is briefly described below.
The line level stage is driven via high quality Noble volume and balance controls. The amplification stage
uses a 6SN7 anode follower. Again, AN paper in oil and Black Gate capacitors and 1% premium resistors
are used throughout. Adjustable gain and output impedance is performed by the selectable application
of negative feedback around this stage.
The high voltage power supply uses a 6X5GT vacuum tube rectifier with choke input filtering and vacuum
tube regulation. The vacuum tube regulator employs a dissimilar ECL82 pentode/triode, the pentode as
the power device and the triode section as an error amplifier. The filament voltages are also regulated to
reduce hum and noise.
