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 triodes.
