WA8 Eclipse is the world's first battery-operated vacuum tube headphone amplifier and DAC. Featuring SET Class-A transformer output for transparent sound quality, a built-in 24bit/384kHz DAC, and easy transportability/set-up, it’s 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. Versatile in analog and digital realms, 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. 

The Eclipse operates via external DC power or "off-the-grid" battery operation. Advanced technology provides steady and pristine power to the vacuum tubes and the DAC, offering several hours of play – and the unit is operable during charging. For the first time, high-fidelity and uncompromised sound can be achieved without boundaries. WA8 Eclipse is the ideal audio system for the home, in the office or in hotels around the world.
