SRM-400S is a rock-solid performer

Soundstage Australia

Enhanced sound quality

The SRM-400S utilizes a newly designed power transformer and all-stage FET amplification, resulting in lower distortion and a wider frequency response. This translates to a more accurate and detailed listening experience.

Improved build quality

The unit features a sturdier aluminum chassis that minimizes vibrations and external noise interference, contributing to a cleaner audio output.

Versatility

It offers both RCA and XLR inputs, making it compatible with a variety of audio sources.

In my view, SRM-400S is a rock-solid performer that deserves the attention of anyone who’s looking for an affordable electrostatic headphone amplifier capable of driving high-end earspeakers. Its sound is undistorted, sparkly and exciting to a degree that puts it tantalisingly close to amplifiers with a much higher price tag. It would be well worth your effort to audition it when you can.
