A few of the insights about the CH Precision L10 preamplifier and M10 power amplifier. The M10 power amp was split into two boxes like the preamplifier. One cabinet is dedicated to the power supplies and the other one is the audio box. Unlike the 1 Series, power cords are needed only for the power supply cabinet as the external power supply box is not optional. For reference, the size of the L10 is identical to an L1 & X1 combo, while the M10 cabinet size is larger than a single M1.1. It is 440 x 270 x 500mm.
