STAX SRM-T8000 silver

The SRM-T8000 is Stax’s latest flagship electrostatic headphone amplifier using hybrid technology. It employs two 6922 tubes in the input stage, driving a Class A semiconductor output stage. The vacuum tubes are isolated in a separate section comprised of a vibration-resistant damper and protective cover to eliminate vibration and noise. The large, high-capacity toroidal transformers and carefully selected, high-quality parts enable the highest level of sonic refinement.
