Woo Audio’s Jack Wu was in person to debut his new Woo Audio WA23 Luna amp ($9000), which he paired with Abyss's new semiopen-back Diana TC planar headphones ($4495).
Only minimal information was available on Wu’s new amp, but he revealed the following: The WA23 Luna is an single-ended triode design that can serve as a headphone amp or a preamplifier. Power ratings remain a secret, but Wu said the Luna is a high-gain, point-to-point design. It draws watts from a pair of Electro Harmonix 2A3 power tubes; also on board are two 6C45 driver tubes and a 5U4G rectifier tube. It can drive a variety of headphone designs, Wu said.
