Overview

Introducing the WA24 20th Anniversary Edition, a masterpiece born from two decades of innovation and passion at Woo Audio.

Twenty years ago, Woo Audio began its journey with the creation of the WA1, an innovative vacuum tube amplifier. Built in a small apartment in Queens, New York, by a father and his two sons, this amplifier was crafted from readily available components sourced from local electronics stores like RadioShack and surplus outlets. The WA1 demonstrated an impressive ability to enhance the sound of the modest Sennheiser HD650 headphones, inspiring the team to pursue new ways to improve the listening experience for music lovers. Now, in celebration of its founding in 2004, Woo Audio proudly introduces the WA24 20th Anniversary Edition. The next chapter begins now.

Redefining the Listening Experience

Built with knowledge from twenty previous amplifiers, the all-new WA24 is a reference-level amplifier engineered to redefine your headphone listening experience. It brings you closer to the music than ever before, immersing you in the artist’s true intent with stunning clarity and detail. Unveiled in its purest form, every note and every subtle nuance is delivered with breathtaking precision, creating a soundstage so immersive that you’ll feel like the performance is happening live, right in front of you. The anodized gold 20th Anniversary plaque symbolizes Woo Audio’s commitment to producing long-lasting products for a lifetime of musical enjoyment.
