Stax SRM-252S Solid State Energiser - NEW OLD STOCK

The Stax SRM-252S Energiser is Stax's entry-level amplifier for use with its range of electrostatic Earspeakers. It is a direct-coupled solid-state class A design.

The STAX SRM-252s amplifier is able to be connected to various sources using just a standard 3.5mm jack  connection. Enabling devices such as CD Players, Portable Audio Devices or PC's to connect to the Class-A DC  amplifier which sits in a compact CD jacket sized aluminium casing. The SRM-252s' aluminium casing helps to  dissipate any heat created by the class-A amplification and with no coupling capacitors it manages to reproduce  the finest, most delicate of nuances.

The STAX SRM-252S Headphone Amp has a simple design that excels in sound quality employing the carefully selected newest high-voltage transistors and low-noise FETs. The output stage featuring the emitter-follower configuration reinforces the driving performance and also realizes the smooth sound quality. Moreover, the Class-A Amplification throughout the stages with no coupling capacitors reproduces exhaustively the finest nuance of music. Although the STAX SRM-252S Headphone Amp includes a Class-A DC Amplifier in a compact CD Jacket Size Case, the internal heat is effectively dissipated through the chassis of aluminum extrusion material to improve the reliability over a long period of time. Also, the parallel output terminal was added to distribute the source signal so that a loud speaker may also be simultaneously used when source equipment has only a pair of output terminals.
