Stax SR-X9000

A bigger transducer allows for more air to be moved, with less distortion. The comparisons to legendary predecessor SR-009/S will always be there, but don't let that condition your first listen – SR-X9000 walks its own path sonically. Of course, this end-game begins with typical electrostatic traits and is clean as a whistle.

Transparency is a hallmark of Stax owing to Multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) technology – now, MLER-3 builds on two decades of Omega series breakthroughs, in a flagship of the future. 

Superb acoustics from the metal mesh electrode let's air waves propagate as a straight plane towards the ear, enhanced thermocompression bonding allowing SR-X9000's electrostatic driver to achieve low air resistance and minimise stator reflections.

There is a naturalness to behold about Stax's proudest release that's helped by an angled mesh guard reflecting sound back directly towards your ears rather than towards the side of the head.

Soundstage from SR-X9000 appears in front of you following a frontal arc of soundstage – something that could only see Stax's legendary imaging qualities enhanced.

All this in a package that'll stand the test of time, like its company. Tough machined aluminium cups minimise the effects of resonances and vibration, with replaceable cables standard on SR-X9000 to allow easy replacement in the unlikely event the cord fails.

Hear this to start 2022 with a bang, via Stax's new generation of energisers – the SRM-700S, SRM-700T, and SRM-T8000. Also browse Stax's other electrostatic earspeakers here, or all our other headphones here.
