SRM-T700T Valve Energizer
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 “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.
The T700T features switchable RCA and XLR inputs. RCA parallel out and bypass volume control switching.
The newly developed large-sized aluminium insulator combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.
Like the successful T8000 energizer, the T700 features a new updated look which brings Stax into the modern world in terms of styling.
Please note that this device can only drive STAX’s electrostatic earspeakers
