Grandioso M1X

Redefinition of a power amplifier with the flagship model

Categories: ,

Employing a newly developed super junction bipolar transistor the ESOTERIC SJ-BJT01, the Grandioso M1 has evolved into the X Edition.

An all-new Grandioso M1X, a power amplifier that draws music from dignified silence to effusive passion.

  • The world’s first* bipolar transistor with high-current amplification factor and low on-resistance super junction, the ESOTERIC SJ-BJT01 for power amplifier element
  • Toroidal-core transformers exclusive for both voltage amplification and current amplification stages
  • Over-sized ESOTERIC’s custom-designed toroidal-core transformers with over 3,000VA of core-size for the current amplification stage
  • New custom-deisgned capacitor with as high as 60,000uF capacity for the power supply section of the current amplification stage
  • ES-LINK Analog input, a unique current transmission method, in addition to the conventional balanced and unbalanced inputs
  • IDM-01 (Integrated Discrete-Amplifier Module) designed for the Grandioso C1X applied to the ES-LINK Analog circuit
  • Audio signal control with FET elements that are not affected by mechanical contacts
  • Copper foil for conductive patterns on power supply and amplifier printed circuit boards
  • Balanced-design buffer amplifier circuit on input stage
