STAX SRM-T8000

The STAX SRM-T8000 is STAX's current flagship electrostatic headphone driver, a hybrid design that combines 6922 vacuum tubes in the input stage with a Class-A solid-state output stage, delivering 470V RMS maximum output voltage and 60dB of gain for the most demanding STAX electrostatic earspeakers. The definitive modern expression of STAX's hybrid amplifier philosophy.

Type and Technology

Hybrid electrostatic headphone driver, vacuum tube input with Class-A solid-state output. Two 6922 tubes in the input stage, isolated in a vibration-proof damper and shield cover to eliminate microphonics and noise. Class-A solid-state output stage for maximum output voltage and control. High-capacity large toroidal transformers. 60dB gain. 470V RMS maximum output at 1kHz. Volume control bypass for external preamplifier use. Two STAX PRO bias outputs. Balanced XLR and dual unbalanced RCA inputs. US voltage: 120V/60Hz.

Sound Character

Combines the tonal warmth and harmonic dimensionality of vacuum tube input amplification with the control, output voltage, and dynamic authority of a Class-A solid-state output stage. The SRM-T8000 draws the best qualities from both technologies, a presentation that is simultaneously tonally engaging and technically capable of extracting everything the SR-009S and SR-X9000 can offer.

Build and Finish

STAX's most substantial energizer at 7.3kg and 320 x 103 x 395mm. Tubes are mechanically isolated from the chassis to eliminate vibration-induced noise. High-quality selected components throughout. 1-year US limited warranty.

Best For

STAX SR-009S and SR-X9000 owners who want STAX's own flagship driver for the most complete system performance, and those who want the tube character of STAX hybrid amplification at its most refined.
