Woo Audio WA12 Zircon Flagship Headphone Amplifier

If a solid-state headphone amplifier that sounds like vacuum tubes is what you want, only Woo Audio could build it.

This is the WA12 Zircon - a solid-state headphone amplifier reimagined by Woo Audio. Engineered to deliver the "house sound" our customers know and love about our vacuum tube amplifiers in a user-friendly and elegant form-factor.

The WA12 Zircon can drive every dynamic, planar magnetic, and ribbon headphone on the market today and into the future. Those who enjoy IEM (in- ear monitors) will be impressed by the ultra-low noise floor of the amplifier, allowing flagship IEMs to truly shine.

Design Philosophy
WA12 Zircon draws inspiration from our WA24 20th Anniversary Edition's design principle: a simple circuit produces the best sound.

Design
Class-A, fully balanced, zero feedback. Featuring eight current power amplifiers per channel, the WA12 achieves optimal power delivery for any IEM or headphone. It includes an unprecedented Dual Power Supply (Dual PS), supporting both pure-battery mode and AC power mode via an in-house custom linear power transformer. Pure-battery mode offers sound purity, precision, and refinement not found in other solid-state headphone amps. With a flip of a switch, WA12 Zircon transitions seamlessly to AC power mode for uninterrupted music enjoyment.

A User-friendly Masterpiece
WA12 Zircon is a headphone enthusiasts' dream come true. It features three dynamic headphone outputs (4-pin XLR, 4.4mm balanced, and 6.3mm unbalanced) and one direct-drive TR (True-Ribbon) output via 4-pin XLR. Connect all your favorites at once and select between them with a press of a button.

The WA12 Zircon is built like a fortress to last a lifetime. Its dual-layer chassis is precision-machined from a solid block of billet aluminum, providing a stable and resonance-free foundation for the audio components housed inside. Dedicated metal compartments carved out from an aluminum block to shield the audio components from airborne interference or EMI noise. All your music will sound pure and faithful to the original masters.
