SKU: M2.2 220 W class A/AB hybrid
Model 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.

The M2.2 is a masterful blend of design and engineering simplicity. It assures the recreation of a three dimensional sound stage in the home, recording studio, etc. without boundaries and limitations. A distinctive feature of the M2.2 is the extraordinary transparency and localization of perceived sound.

It 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.

The 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), continuous. The 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.

Each 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 vibrations. This plays a significant role in assuring the absolutely unique clarity and micro-resolution during sound reproduction.

The M2.2 works on all world AC line voltages.
