Our Thoughts RADAR AI

A bargain at £349, comfortably below the comparable-market 25th percentile of £386 and well under the £423 median.

The WA6 remains a seriously capable, characterful tube amplifier: its Class-A, transformer-coupled design gives a smooth, warm presentation while the impedance switch makes it suitable for both sensitive headphones and high-impedance models. Point-to-point construction and a simple, serviceable circuit are appealing to long-term owners. Since the listing gives no condition or tube information, confirm that both channels are quiet, the impedance switch works, and the supplied 5AR4 and 6DE7 tubes are healthy. Even allowing for a possible tube refresh, £349 leaves useful headroom and looks like a worthwhile buy.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Woo Audio

Woo Audio is a New York-based high-end audio company founded in the mid-2000s, with 2006 widely cited as its launch year. It was built by the Wu family, with Jack Wu as the public face of the brand and key design influence, alongside family members who helped shape the company’s early growth. Its roots are in tube electronics and a strong appreciation for live sound, which has remained central to its identity.

The brand is best known for vacuum-tube headphone amplifiers, especially models such as the WA series, along with electrostatic headphone amplifiers like the WES. Woo also makes a smaller range of speaker amps, plus related audio accessories and cables, while its website and retail focus remain centered on amplification and headphone-oriented listening rather than source components or turntables.

In the market, Woo Audio sits firmly in the boutique high-end niche. It is respected among headphone enthusiasts for handcrafted, valve-based designs, substantial build quality, and a distinctive sonic character often associated with warmth, scale, and refinement. It is not a mass-market brand; instead, it appeals to serious buyers looking for premium, specialized amplification with a strong American-made identity.
