Electrifying Audio

While you can conjure up excellent audio quality with dynamic headphones, they still rely on moving parts to transfer the sound. For a frictionless and nearly distortion free process, electrostatic systems transfer a static electric charge onto a film without resonances or energy storage, making for unparalleled audio reproduction. Giving you the earspeakers and tube-based electrostatic amplifier necessary to get charged up, the Stax SRS-4170 delivers first class audio quality.

The Most Powerful Element

The earspeakers, the SR-407, feature the same sound element as Stax’s top of the line model, the SR-507. A wide diaphragm utilizes similar principles to how sound is originally recorded, giving you a more faithful rendering. Encased in tough resin, the active element builds on over 30 years of release to bring the cleanest and most reliable sound in Stax’s history. The earspeakers were finished in thin-film “Super Engineering Plastics” material, which protects the unit from temperature and humidity interference while enabling rich lows and delicate highs.

Stax on Stax

Providing the necessary juice for the earspeakers, the Class-A electrostatic amplifier, the SRM-006tS, was engineered to eliminate every possible source of distortion. Relays are close to the input for a short signal path, high-voltage dual vacuum tubes boost the output stage, two-stage amplification with low noise FET expands the input stage, and the mutual interference between the amplifier and earspeakers has been eliminated by alternating signals. For impeccable sound quality and aesthetics straight from the future, give in to your inner audiophile and pick up the Stax SRS-4170.
