WA5 / WA5-LE Single-ended Triode
Class A 300B Tube Amplifier
Handcrafted in New York, U.S.A. since 2008, the latest
2015 edition WA5 and WA5-LE are prominent examples of trickle down technology. Our 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 powerhouse. 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 level 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.
