The STAX SRM-353X is an exclusive driver unit (amplifier) from STAX. This driver unit reproduces sound over a wide range of frequencies and gives you audio that sounds natural thanks to the FET and improved emitter.

The STAX SRM-353X also looks good. Each component is handpicked to ensure that it does not age. At the same time, the non-magnetic aluminium alloy chassis lets you show off this driver unit to everyone.

Please note that this device can only drive STAX’s electrostatic earspeakers.

Features:

  • Original low-noise dual FET at first stage as well as all-stage direct coupling class-A DC amplifier configuration with no coupling capacitor has realized natural tone quality with much amount of information.
  • Further improved emitter follower at output stage has enabled wide-range reproduction resulting in both the extended dynamic range at high frequency and the improved tone quality.
  • In addition to RCA input terminal, XLR balanced input terminal is provided to connect to wide range of audio equipment. ●Custom-made 2-axis 4-gang volume controller is employed.
    ●Extravagant non-magnetic aluminum alloy chassis of STAX tradition is adopted.
    ●Components with little aging characteristics are selected carefully in consideration of tone quality and performance.
