Woo Audio is a family-run maker of tube headphone amplifiers from New York, started by Wei Wu and his sons Jack and Zhidong in a small apartment in Queens. It grew out of an amplifier Wei Wu built for his own Sennheiser headphones after finding the commercial models of the time unsatisfying, and it now sells tube amplifiers, electrostatic amplifiers and digital sources from a workshop in Long Island City.
Range & what it's known for
The core product is the WA series of headphone amplifiers, which includes the WA2, WA6, WA7, WA8, WA11, WA22 and WA33, with the WA5 among the larger models. For electrostatic headphones there are the 3ES, WES and GES, and the WA234 MONO is a pair of mono-block amplifiers. The compact TUBE mini is at the small end of the range, and many of these models have been produced across several generations, each updated over the years. Woo Audio also builds loudspeaker amplifiers and digital products, including the WDS-1 DAC and the WTP-1 transport, so a complete source and amplifier chain can come from the same maker.
Who owns it and where it's made
Ownership stays with the Wu family, and the business is still run by the people who started it. Jack Wu handles pre and post sales, marketing and quality control and leads product vision. Every amplifier is designed, hand assembled and shipped from the New York workshop, and warranty service and product support are handled by a team based in the United States.
The lineup in this catalog
Headphone amplifiers make up the core of the listing, with several further items in other categories. A small Woo amplifier sells for about USD 500, while the largest WA models cost well over USD 10,000.
Who it's for
For a headphone system, Woo Audio offers a tube amplifier assembled by hand in the United States. A compact model such as the TUBE mini or WA7 is the first rung, with the WA22, WA33 and the WA234 mono-blocks as the upgrade path. Owners of electrostatic headphones have their own branch in the 3ES, WES and GES, and the WDS-1 and WTP-1 complete a system.
