Product Details

↓ Details provided by Woo Audio


WA5-LE (Lite Edition) is a single-ended triode (SET), class A tube amplifier. It differs from the highly acclaimed WA5 only in that it is a dedicated headphone amplifier and cannot be used to drive loudspeakers. In all other respects, WA5-LE is identical to the WA5 and offers the same captivating sound quality. WA5-LE is designed around the audiophiles' favorite 300B vacuum tube. This tube provides exceptional transparency allowing the listener to experience music close to a live performance.
