Woo Audio WA8


Special order, 1-2 weeks.

Woo Audio’s epic WA8 Eclipse is the world's first battery-operated vacuum tube headphone amplifier. Featuring SET Class-A transformer output for transparent sound quality, a built-in 24bit/384kHz DAC, so high fidelity audio listening is possible anywhere. With its high power output, the Eclipse is capable of driving high-end headphones of 8–600 ohm impedance, while its ultra-low noise circuitry is ideal for in-ear monitors. While portable, the Eclipse boasts a robust military-grade vacuum tube design rated for 5,000 hours of life. It offers two- or three-tube operation to tailor the sound quality to a variety of headphones and in-ear monitors.

The Class-A, Single-ended Triode topology uses ultra-efficient OCC single crystal copper output transformers offering high bandwidth and low loss. The Eclipse also uses an audiophile-grade ESS SABRE Reference 24bit/384kHz DAC, excelling with hi-res music files and compatible with Apple iOS and Android devices. Advanced battery power management offers steady and pristine source to both amplifier and DAC. Transportable size and form-factor, full-sized desktop-class amplifier/DAC performance.
