| The M3 is a level
3 product, meaning that it conforms to strict technical and component
quality criteria. All areas of design requirements have been thoroughly
reinvestigated with new solutions being sought, therefore creating
a pre-amp that performs way above any other at the price point.
The M3 pre-amp is the first in its price category to use a complementary
dual mono power supply, incorporating valve rectification and double
choke smoothing. High quality Cerafine capacitors are used and the
unit is completely hard wired throughout.
The audio circuit
is also hand made and hard wired using Audio Notes own tantalum
film resistors, pure copper foil signal capacitors and Black Gate
de-coupling capacitors throughout.
The most unusual feature in the M3 is the line output stage, which
is configured as a small power amplifier stage with a 5687WB double
triode per channel. An output transformer is then coupled to the
output signal which serves as an interface to the power amp being
used.This allows the M3 to utilize not only two sets of single ended
RCA outputs but also a 600 Ohm fully balanced output using a Lemo
type connector. This unique way of transformer coupling the output
stage means that the M3 can be used with any power amplifier whether
valve or transistor.
The phono section of the M3 uses three 6072A double triodes in
a cascode input configuration with passive RIAA equalization, Audio
Note copper foil paper in oil capacitors and a single 6072A as an
anode follower which in turn feeds the line stage via high quality
ELMA switches.
M3 is available in phono, line-only and RIAA versions.
