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; 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.
