Electrostatic Earspeaker Amplifier

Electrostatic Earspeaker Amplifier

This hybrid STAX amplifier combines the speed and precision of a low-noise FET input stage with the warmth and musicality of classic 6SN7 vacuum tubes. Designed for electrostatic headphone enthusiasts seeking both clarity and emotion, it delivers a spacious, highly detailed sound with exceptional transparency and smooth, natural tonal balance.

At the heart of the design is a custom-made low-noise dual FET first stage paired with a 6SN7 vacuum tube output stage, a classic tube renowned for its simple yet powerful sonic character. The hybrid amplifier architecture combines the strengths of both technologies, producing fast transient response, impressive clarity and a beautifully open soundstage. Premium non-inductive winding resistors from VISHAY are used within the circuitry to further refine signal purity and stability. The result is an amplifier capable of reproducing music with outstanding realism, preserving delicate detail while maintaining the rich warmth and spacious presentation vacuum tube designs are loved for.
