The WA24 20th Anniversary Edition is a valve headphone amplifier from Woo Audio, released to mark the company's twentieth year. Woo Audio has specialised in valve headphone amplification for two decades, and this edition is a large, heavy design in its range.
Key specs that matter
Woo Audio rates the response from 10 Hz to 40 kHz, a wide bandwidth that extends beyond the audible range at the top end. The chassis measures 390 x 270 x 197 mm and weighs 17 kg, which is substantial for a headphone amplifier.
Engineering and use context
The weight comes from the transformers and power supply of a valve circuit rather than from a compact solid-state board.
Pairing
In line with the rest of Woo Audio's valve amplifier range, the WA24 20th Anniversary Edition is designed to drive a wide range of headphone impedances, so it can be matched with both low- and high-impedance headphones.
