Overview

WA8 is NOT a portable headphone amplifier. It is the world's smallest all-tubes headphone amplifier and DAC with performance that rivals full-size systems and can operate on AC power or on battery for the best sound quality.

Featuring SET Class-A transformer output for transparent sound quality, a built-in 24bit/384kHz DAC, and easy transportability/set-up, capable of driving high-end headphones of 8–600 ohm impedance, while its ultra-low noise circuitry is ideal for in-ear monitors.

While small, 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 and up to DSD128 DAC, excelling with hi-res music files and compatible with Apple iOS and Android devices.

The Eclipse operates via external DC power or battery for noise-free "off-the-grid" 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 or the office.
