Top-quality sound element

Fixed electrodes machined through stainless photo etching have been employed for the SR-L300, delivering a balance of rich deep bass response, delicate high frequencies and beautiful mid-range.

Slide-type arc assembly

The arc assembly of the SR-L300 uses a clever steps slider mechanism for exact head-pad height adjustment.

New low-capacitance OFC wide cable

The core wires use specially selected OFC cable in combination with a specially wide parallel structure across the whole cable to lower the capacitance between each wire strand.

High-quality artificial leather earpad

The high-quality flexible artificial leather ear pads ensure the SR-L300 is beautifully comfortable to wear

STAX SRM-252S Energiser (driver unit)

The SRM-252S is an exclusive driver unit (amplifier) for driving STAX ear speakers with PRO-bias 5 pins. Its line input can directly connect to the audio output terminal of a CD player, portable audio player and PC. With a simple design that excels in sound quality, it employs carefully selected high-voltage transistors and low-noise FETs. The output stage features an emitter-follower configuration that delivers superb driving performance.

Moreover, the class-A amplification throughout the stages has no coupling capacitors and reproduces the finest nuances in the music.

Although the SRM-252S includes a class-A DC amplifier in a compact CD size case, the internal heat is effectively dissipated through the aluminium chassis extrusions to improve the reliability over a long period of time. Also, the parallel output terminal has been added to distribute the source signal so that a loudspeaker may also be simultaneously used when source equipment has only a single pair of output terminals.
