The STAX SRM-252S Headphone Amp is an exclusive driver unit for driving the STAX Ear Speakers with PRO-Bias 5 Pins. The SRM-252S Headphone Amp's line input can directly connect to the audio output terminal of CD Players, Portable Audio Players or your PC.
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.
