Stax SRM-700T Vacuum Tube High-End Electrostatic Driver Click above to see Joe talking about a headphone experience like no other The first stage is a custom-made low-noise dual FET while the second stage is a clear, high slew-rate vacuum tube 6SN7. The tube output offers warm and spacious music reproduction. Together, this hybrid design delivers a wonderfully precise, detailed sound with overtones of tube warmth. A great combination. Features 6SN7 achieves a highly transparent sound Non-inductive winding resistors with the least inductance High-definition film capacitors Hand-selected matching FET EMI shielded volume control Volume control bypass switching Switchable RCA and XLR inputs. RCA parallel out. Features newly developed large-sized aluminium insulators, combined with new vibration-proof material plus high frictional coefficient.
