STAX T80009S Supreme Electrostatic System
SR-009S uses multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) established with SR-009 has evolved to MLER 2. The finish and etching process that smooths the edge of the electrode opening reduces air resistance and further improves sound permeability. Also, the electrodes themselves are gold plated with high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, due to the effect of reducing the electric resistance of the electrode itself by gold plating, we have opened up a new ground for high speed, clarity, silky details, and powerful texture.
SRM-T8000 is Stax's latest flagship electrostatic headphone amplifier utilizing hybrid technology. It employs two 6922 in the input stage, driving a Class-A solid-state output stage. The vacuum tubes isolated in a separate section made of vibration-proof damper and shield cover to eliminate vibration and noise. The high-capacity large toroidal transformers and selected high-quality parts allow the highest refinement in sound.
