Key Product: WA7 Fireflies valve-powered Headphone amplifier/USB DAC ($999)
At Rocky Mountain Audio Fest 2012, Woo Audio showed a prototype of the WA7 Fireflies, but by CES the product had achieved full release status. Basically, the WA7 is a valve-powered headphone amplifier driven by a pair of 6C45 valves (vacuum tubes), and that also incorporates a 32/192 (no, that’s not a typo) high-resolution USB DAC.
Apart from sound quality, the WA7 Firefly is also impressive for its looks. Indeed, it is precisely the sort of component that will leave you wondering whether to listen to it or to simply stop for a moment to appreciate it as a sculptural object. Either way, it promises rewarding experiences for the owner.
