Know before you buy
By separating the power supply into its own dedicated chassis, the WA5 prevents electromagnetic interference from reaching the sensitive audio signal path. This isolation results in a lower noise floor and a cleaner, more transparent sound.
Yes. The amplifier features user-selectable HI/LO impedance and level settings, allowing you to fine-tune the output to match the specific electrical requirements of your headphones for optimal synergy.
Yes, the WA5 is designed with global voltage compatibility, meaning it can operate on any standard voltage from 100V to 240V without the need for an external power converter.
Absolutely. The WA5 is a true integrated amplifier that includes dedicated circuitry for both headphones and speakers, with a simple switch to toggle between the two outputs.
Like all tube amplifiers, the WA5 requires periodic tube replacements once they reach the end of their lifespan. The unit features autopolarization, which simplifies the process by eliminating the need for manual bias adjustments when swapping compatible tubes.
The amplifier is equipped with one balanced XLR input and two unbalanced RCA inputs, providing enough flexibility to connect multiple high-end audio sources simultaneously.
