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.
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.
