Stax SRM-700t Earspeaker Driver

The newly designed Stax 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.

Stax SRM-700t Key Features and Specifications;

Features:

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 tubes realize a highly transparent sound
• Non-inductive winding resistors with the least inductance
• High-definition film capacitors are used
• Hand-selected matching FET
• Volume control is EMI shielded
• Bypass volume control switching
• Switchable RCA and XLR inputs. RCA parallel outputs
• newly developed large-sized aluminium insulators combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.
