Woo Audio WA5-LE Tube Headphone Amp
Visit Manufacturer's Site

Handcrafted in New York, U.S.A. since 2008, the latest 2015 edition WA5 and WA5-LE are prominent examples of trickle down technology.


Woo's engineers
were able to apply much of the no compromised
design philosophy from our flagship product WA234
MONO, the world’s first mono-block headphone and
speaker amplifier
into a dual chassis stereo power-
house. Like it’s big brother, the WA5 / WA5-LE is an all
tube design, utilizing the 6SN7 tube for driver, 300B
tube for power and 274B tube for rectifier.
The marquee feature of WA5 / WA5-LE is the user
selectable HI/LO power, HI/LO impedance and HI/LO
output switches located on the front panel.
When used in conjunction, the user can optimize the
synergy between amplifier and headphones to
achieve the ideal pairing.
Whether you choose WA5 or WA5-LE, the glorious
sweet sound of the 300B tube has never been so
accessible and versatile.
