![[Customized] Woo Audio WA22 (1st gen) Fully-balanced Headphone Amp - Silver](https://i.ebayimg.com/images/g/CYYAAeSwIftqtqn4/s-l225.jpg)
RADAR is a price search engine. We link to the original listing — we never sell direct. Transactions happen on the source site.
The asking price is a bit ambitious at US$1,599 against a recent used median of US$1,463 and a 75th percentile of US$1,531. It’s not wildly off, but it’s above the current typical range enough that I’d want a little extra to justify it.
That said, the WA22 is a respected fully balanced tube headphone amp with real muscle and a big, fluid presentation that pairs well with demanding planars and high-impedance dynamics. If this one is clean and includes any meaningful tube upgrades or original packaging, the premium is easier to swallow; otherwise, I’d treat it as a buy only if you really want this model and can’t wait for a better-priced example.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
