This is a strong deal. At US$599, it lands well below the US$740 25th percentile and far under the US$846 median of the recent comps, so this is priced like a bargain rather than a merely fair ask.
That makes it attractive because this amp/DAC is well-liked for its clean, polished sound and compact all-in-one convenience, especially for a desktop setup where you want simple wiring and a premium feel. The included cables and accessories add practical value at this price, and the main buyer check is straightforward: confirm power-up, output on both headphone and line paths if applicable, and that any included tubes or accessories are complete and working.
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.
