What HiFi

Japanese manufacturer STAX have been developing headphones since 1938 and electrostatic headphones since 1959. Utilising electrostatic technology in their ‘earspeakers’ that are widely regarded as the best headphones available today, STAX electrostatic earspeakers are widely used throughout the world by discerning audiophiles, professional musicians, and recording companies to enjoy and monitor sound thanks to the superb sonic quality that they offer.

An electrostatic transducer is a speaker design that employs a high polymer film of several microns thick as the diaphragm for far less mass than paper or mylar cones or metal type diaphragms. Since electrostatic elements use no magnets, they are free from magnetic hysteresis distortion that is prominent in dynamic type headphones.

Who is this for?

The Stax SR-009S is an open-back electrostatic earspeaker with improved bass response and a tamed treble peak relative to the original SR-009, sitting near the top of Stax's range. It suits listeners with a genuinely reference-level system who want one of Stax's most acclaimed earspeakers.

It demands a top-tier driver unit to perform at its best, and is well suited to pairing with amplifiers such as the SRM-700S or SRM-T8000 for a system where nothing is holding the earspeaker back.

It's a strong choice for serious electrostatic enthusiasts, sitting just below the SR-X9000 MkII as Stax's current absolute flagship earspeaker.

Stax SR-009S Electrostatic Earspeaker

The very first thing to say is that if you haven’t heard a pair of electrostatic headphones, you are going to be blown away if you listen to a pair of SR-009S earspeakers in combination with the Stax SRM-700S.

The SR-009S is a masterful achievement that expands upon the SR-009’s strengths, offering heightened detail and focus, more nuanced and expansive dynamics, and superior bass.

In sum, the Stax SR-009S is a truly world-class headphone in 2021, and without hearing the Stax’s X9000, may well be one of the best headphones on the planet. It’s unique combination of musicality and technical prowess makes puts it in the Champions’ League of headphones, a league inhabited by the HIFIMAN Susvara, Abyss AB-1266 Phi TC, the Raal SR1a, and so forth.
