The Grandioso M1X is an all-new flagship monoblock amplifier with a number of the latest technologies including a world's first* super junction bipolar transistor, the ESOTERIC SJ-BJT01, and by renewing the previous M1 throughout, the Grandioso M1X draws music from dignified silence to effusive passion.
A trigger function allows the Grandioso C1X, a linestage preamplifier to turn on and off the M1X in sequence, while the ES-LINK Analog connection guarantees high quality analog audio signal transmission between pre-amplifier and power amplifier.
