STAX SRM-270S Electrostatic Driver Unit

The newly developed SRM-270S Driver Unit by STAX Audio, setting a new benchmark for entry-level electrostatic audio system.

The SRM-270S has updated the design of the previous model (SRM-252S) by improving the quality of the RCA pin jack, adopting a 3 mm thick front aluminium panel, and adopting an aluminium extrusion case that has been enlarged and has improved heat dissipation.

The first stage of the amplifier is equipped with the latest low-noise FET, and the output stage is equipped with an improved emitter follower circuit.

This latest design know-how that follows the trend of driver development in recent years is condensed into a compact housing. Since the input and output are equipped with parallel out terminals, it can be easily combined with your current system.

Features
