Hi, I'm the original owner of this Woo Audio WA22 Class A push pull fully balanced headphone amp. This is a Gen1 version which doesn't have the preamplifier output on the back, but is more powerful. Give me more power over a pre any day. This will run pretty much any set of headphones. It has dri...
Excellent condition is a nice start, but at A$1,999 this sits just under the 25th percentile of the A$2,037–A$2,072 comp spread, so it reads as a genuine bargain rather than merely fair. Against a median of A$2,054, you’re buying a well-known tube headphone amp a touch below the going rate, which is exactly where a used listing should get attention.
The WA22 is respected for its big, spacious presentation and strong synergy with high-impedance and many planar cans, and clean examples tend to hold demand well. If the tubes are healthy and the included cables/accessories are complete, this is the kind of listing that’s worth moving on quickly; the price leaves little room for haggling, but it’s already in buy-now territory.
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.
