Like the Xs 300, the Xs 150 was developed through constant and thorough innovation. After years of SIT device experimentation—followed by real-world deployment in Nelson's First Watt designs—our circuit modifications capture the unique, tube-like sonic footprint of SITs using the higher-output MOSFET devices in the Xs series. The result is unparalleled, fatigue-free listening enjoyment.
The Xs 150 delivers the color and ease of classic SIT voicing with the drive and bandwidth of modern Class A—built for long, happy sessions.
