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.

The first stage is a custom-made low-noise dual FET while the second stage is clear and high slew-rate vacuum tube 6SN7. The tube output offers warm and spacious music reproduction.


6SN7 realizes a highly transparent sound



Non-inductive winding resistors with the least inductance


Hand selected matching FET

High-definition film capacitors are used

Bypass volume control switch

Volume control is EMI shielded

Switchable RCA and XLR inputs. RCA parallel out.

The newly developed large-sized aluminum insulator combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.
