M2.2 is the most powerful amplifier in the line
of LAMM hybrid and solid-state audio equipment.
It is one of the best creations of its designer's
professional career -- a result of years of
intensive research directed at attaining the most
accurate reproduction of recorded music.
M2.2 is a masterful blend of design and engineering
assures the recreation of a three dimensional sound stage
in the home, recording studio, etc. without boundaries and
distinctive feature of the M2.2 is the extraordinary
transparency and localization of perceived sound.
is a pure class A amplifier, with the exception of the
output stage which operates in a highly biased A/AB mode. The M2.2 incorporates high-speed MOS-FET
transistors in the output stage with no overall feedback. Special switch-selectable biasing circuit maintains
the optimal idle current of the output stage for all load
conditions between 1-16 Ohms. It is a hybrid design with the one specially
selected 6922 vacuum triode.
M2.2 is conservatively rated to deliver 220 Watts into 8
and 4 Ohms in a highly biased A/AB mode (high and low
impedance settings, respectively); 440 Watts into 2 Ohms,
and 600 Watts into 1 Ohm (low impedance setting),
M1.2 can drive any known speaker. The harmonic structure remains intact regardless of
the speaker load, while the extreme clarity is maintained
at all power levels.
amplifier is carefully constructed and hand-crafted with
the finest materials and parts currently available, some
of which include military graded low noise DALE metal film
resistors; PRC wire wound resistors; ELECTROCUBE and
ROEDERSTEIN film capacitors; high frequency switching
grade CORNELL DUBILIER electrolytic capacitors; BOURNS
multi-turn potentiometers; HAMMOND filter chokes; military
graded low noise long life vacuum tubes; high quality
heavy duty gold-plated binding posts and RCA jacks;
gold-plated NEUTRIC XLR connectors, and CAMAC-type coaxial
connectors from FISCHER. Special attention was given to designing the
toroidal power transformer, which has no mechanical
contact with either the transformer cover or the chassis
and is suspended in a special encapsulant that almost
completely absorbs even the residual mechanical
plays a significant role in assuring the absolutely unique
clarity and micro-resolution during sound reproduction.
M2.2 works on all world AC line voltages.
