Stax Bundle Set SR-X1 + SRM-400S

Experience the pinnacle of electrostatic audio with the SR-X1 and SRM-400S pairing. The SR-X1 earspeaker delivers an exceptionally pure soundscape through its push-pull electrostatic design, capturing frequencies from DC to 35,000Hz with remarkable clarity. Harmonic distortion remains virtually imperceptible at 0.01% or less, while the heritage-inspired engineering draws from decades of Stax innovation. The medium-sized circular driver features precision-etched electrodes and genuine sheepskin leather earpads for extended listening comfort. Paired with the SRM-400S amplifier, this bundle provides the optimal synergy for discerning listeners seeking uncompromised audio fidelity and an immersive listening experience. The SRM-400S amplifier represents a dedicated solution engineered specifically for electrostatic earspeakers. Built on an all-stage FET configuration, this semiconductor driver delivers pristine amplification with an expansive frequency response extending from DC to 90kHz. With 60dB of gain and maximum output voltage reaching 400Vrms, it provides the substantial power required for optimal earspeaker performance. Harmonic distortion remains exceptionally low at 0.01% or less, ensuring signal integrity throughout the audio spectrum. Flexible connectivity via both RCA and XLR inputs accommodates various source components, while the 580V DC bias voltage is precisely calibrated for Stax earspeaker compatibility. Compact yet robust construction makes this amplifier an essential component for serious electrostatic audio enthusiasts.
