Stax kuulokevahvistin


The Stax SRM-353X is the exclusive driver unit (amplifier) produced in order to drive STAX electrostatic type Earspeaker much more ideally.


Carefully selected high-quality parts of an audio grade further improved the tone quality, and re-examination of circuit details realized

much wider frequency response. XLR input terminal provided enables to connect to the balanced output of audio equipment taking

advantage of its superior performance.


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.
