WOO AUDIO WA7 GEN 3 FIREFLIES. Woo audio is based out of New York. This is the Gen 3 version in Silver. Practically brand new. These are considered to be the best headphone dac/amp by many professionals that I respect. And I love the way they sound. It is a tube amp, which gives it a sweet warmth. I ordered from Woo Audio expecting to need another one but ended up not needing it. If you don’t know about these, google it or go onto YouTube. ( https://youtu.be/t2tSvDGlJcc?si=h6mDnLJNNvfMM2SV ) I took it out of the box and turned it on to make sure nothing was damaged during shipping, and that is it. The build quality is second to none and weighs almost 9lbs. The top is glass. The tubes emit a red glow. I also have a pair of Focal open back headphones that are also practically new if interested.
Spec from website below -
The new 3rd gen now features a built-in linear power supply making the setup a breeze and a one-box solution. In addition, the 3rd gen employs a balanced headphone output driven by a pair of 12AU7 vacuum tubes. The power output is over 1.5w of power per channel @4 Ohms; ideal for a wide range of IEM (in-ear monitors) and power demanding full-sized headphones. The user-replaceable vacuum tubes can be upgraded at any time to customize the sound to the listener's preference. The class-leading performance ESS SABRE DAC allows the user to enjoy music from streaming services such as TIDAL, Qobuz, Apple Music, and Amazon Music HD in lossless resolution.
The new 3rd gen is also a tube preamplifier enabling the user to integrate WA7 fireflies with their home speakers system or drive a pair of desktop-powered speakers.
