SRM-700TThe 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.
High output GT tube “6SN7”“6SN7” GT tube has been adopted in the second stage of the vacuum tube system, while custom-made low-noise dual FET is employed in the first stage. The vacuum tube 6SN7 that has become the original form of 6FQ7 realizes simple and powerful performance. The hybrid type driver has adopted the high-quality non-inductive winding resistor from VISHAY Co. as a load resistance. The clear and high slew-rate vacuum tube sound has been improved further to polish up warm and spacious reproduction.
Low-noise dual FETThe 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. Non-inductive winding resistor with least inductance made by VISHAY Co. Strictly selected pair-matched special FET. High-definition film capacitor made by German WIMA is used.
Rear PanelRCA and XLR inputs are switchable. RCA input supports parallel out. Level control switch that can bypass the volume of the unit. The newly developed large-sized aluminum insulator combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.
