Condition is unknown, but at US$690 this sits below the US$899 median of your recent comps and comfortably under the US$1,497 75th percentile, so it reads as a solid buy rather than an aggressive ask. It’s not a deep-bargain outlier versus the US$596 25th percentile, but it is still priced on the buyer-friendly side of the market.
That makes sense for a portable Woo unit like this: the appeal is strong sound quality in a compact, battery-friendly form factor, with enough reputation behind the brand that it stays desirable on the used market. If it’s clean, holds charge properly, and includes the right charger/accessories, the price is fair-to-good value for a well-regarded portable amp that can still punch above its size.
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.
