The SRM-353X is the exclusive driver unit (amplifier) produced to drive STAX electrostatic Earspeaker headphones.
Carefully hand selected high quality parts of audio grade further improves tonal quality, and achieved wider frequency response from re-examination of circuitry. Newly added XLR input terminal enables connection of balanced outputs of audio equipment taking full advantage of its superior performance.
