LATEST ADDITIONS

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.

Woo Audio, makers of tube electronics, are known for designing great-sounding and great-looking amplifiers intended especially for driving headphones. At an AXPONA a few years back, I became fond of their smaller-scale products, such as their WA7 Firefly, a cube-shaped headphone amp/DAC/preamp now in its third generation.

Why do the names of some headphone brands sound like they originated with marketing flacks or PR hacks? Some brands have natural, fuzzy sounding names, others a sci-fi bent.

Bergenfeld New Jersey’s Dekoni Audio was showing headphone accessories at CanJam, including replacement earpads for major headphone brands, eartips, sprays, wipes, cleaners, and the like. They were also auditioning their new headphones, a reworking of the Fostex T50RP MK3 planar magnetics called the Dekoni Blue.
