Description
Lived in a smoke free environment. 300 or so hours on the tubes. Circle above power button is a silver LED light dim sticker. The blue power light is too bright for my taste. Woo Audio's GES is a great sounding all-tube headphone amplifier for Stax-type electrostatic headphones. It uses 6S4 and 12AX7 vacuum tubes in its circuitry and provides a luxurious and unique listening experience that only tube gear can provide – and Woo Audio is an expert in designing the highest quality vacuum tube components. The 800 volts peak voltage swing of the GES produces a greater dynamic range than many other electrostatic headphone amps, including the Stax. The GES uses push-Pull direct drive, Class-A circuitry using the highest quality internal components, including high-performance Solen and WIMA capacitors and point-to-point wiring. The tube complement consists of four 6S4 power tubes and four 12AX7 driver tubes in premium polytetrafluoroethylene (PTFE) tube sockets. The ALPS potentiometer and power switch provide a great feel during operation and are both exceptionally quiet. Connections consist of two pairs of RCA stereo inputs and one STAX Pro Bias 5-pin EarSpeakers output. The anodized aluminum chassis is available in black or silver.
