The Good Best performance we've ever heard at this price point; stunning design.
The Bad Gets extremely hot; no protection for valves.
The Bottom Line The WA2 breathes phenomenal new life into even the greatest headphones on the planet. It may not rise to the greater heights reached by the more costly Woo Audio gear, but at this price point it blew away everything we've ever heard
Woo Audio WA2 headphone amplifier
We don't subscribe to the belief that older is always better in the audio world, or that the only way to enjoy high quality music is from vinyl, through a vintage valve amplifier, with £300 interconnects. What's important is that it just sounds amazing.
Woo Audio hand-build and hand-wire ultra high-end headphone amplifiers using vintage valve amplification. Whether valves are better than transistors is like asking whether dogs are better than trees -- it's down to preference, and ultimately, what sound you're after.
But a headphone amplifier is highly recommended for higher-end headphones, just as a 1080p plasma HDTV is recommended if you're buying Blu-ray discs. The Woo Audio 2 is in the middle of the Woo Audio amp range, and costs around £640 direct from the manufacturer's Web site.
