The newly designed SRM-700T is a hybrid electrostatic headphone driver. Inspired by the flagship model SRM-T8000, the 700T uses solid-state FET as a driver stage and vacuum tube as the output stage.


  • 6SN7 tubes for a highly-transparent sound
  • Non-inductive winding resistors with the least inductance
  • High-definition film capacitors
  • Hand selected matching FET
  • EMI-shielded volume control
  • Bypass volume control switching
  • Switchable RCA and XLR inputs, RCA parallel out
