Lamm M1.2 reference & Sonus Faber Stradivari Parmenter Sound Lamm Industries M1.2 Reference mono block Class A amplifiers. Model M1.2 Reference represents top of the line in LAMM hybrid and solid-state audio equipment. Power amplifier model M1.2 Reference is a pinnacle of its designer�s professional career -- a result of years of intensive research directed at attaining the most accurate reproduction of recorded music. Unique topology and application of the most advanced technological resources and processes bring the M1.2 Reference to a threshold of excellence in sound reproduction. A distinctive feature of the M1.2 Reference is its presentation of the extraordinary transparency of perceived sound which in turn assures the recreation of a three dimensional soundstage in the home, recording studio, etc. without boundaries and limitations. The M1.2 Reference is a masterful blend of design and engineering simplicity. It is a pure class A amplifier featuring high-speed MOS-FET transistors in the output stage with no overall feedback and special switch-selectable bias/voltage settings for 8- or 4-Ohm operation. The bias setting switch assures the pure class A operation of the M1.2 Reference when matched with a speaker load of either 4 or 8 Ohms, whereas conventional class A designs double the power into 4 Ohms resulting in one fourth of the doubled power in class A and the rest in class AB (learn more about this in FAQ section of our website at www.lammindustries.com/faq/switch.html). The M1.2 Reference is a hybrid design with one specially selected 6922 vacuum triode in the second stage.
The M1.2 Reference is conservatively rated to deliver 110 Watts into 8 and 4 Ohms in pure class A operation (high and low impedance settings, respectively); 220 Watts into 2 Ohms, and 400 Watts into 1 Ohm (low impedance setting), continuous. The M1.2 Reference 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.
