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.

A Masterpiece of Design

Every internal component of the WA24 20th Anniversary Edition is carefully selected and thoughtfully laid out for unparalleled sonic performance. At its core are four custom-made 3A/109E mid-gain, direct-heated triode power tubes, chosen for their exceptionally low noise and long-lasting durability. The amplifier's Class-A single-ended topology ensures the purest amplification possible, while the oversized output transformer-a hallmark of Woo Audio design-delivers maximum power and dynamic range, even for the most demanding headphones.

The WA24 introduces a groundbreaking innovation: the in-house developed STEP-UP Driver. This precision step-up transformer, built with a nano-crystalline core and oxygen-free copper wiring, redefines amplification. By replacing traditional active drivers, such as vacuum tubes or transistors, it simplifies the circuit, reduces interference, and dramatically enhances performance. The two-tier chassis, precision-machined from a single block of high-grade aluminum, balances modern elegance with timeless craftsmanship. Each element is methodically designed for both form and function, with an individually shielded enclosure that minimizes internal electrical noise and microphonics. The result is an extraordinarily low noise floor, making the WA24 one of the quietest and most refined vacuum tube amplifiers ever created.

Enjoy stereo channel precision from the 50mm brass-enclosed Alps Alpine RK50 potentiometer, integrated into a substantial-feel volume knob housed within a precisely fitted, slotted, curved shield, delivering a tactile experience as refined as the amplifier's sound. The sandblasted, anodized body flows seamlessly with its contours, while the elegant coke-bottle-shaped 3A/109E vacuum tubes blend classic design with modern sophistication.
