Pass Labs - XS Pre 2 - Three-Chassis Reference Preamplifier

The XS Pre 2 is designed to disappear completely into the system, allowing recordings to emerge with extraordinary clarity, space, and realism. This fully separate three-chassis reference preamplifier lowers noise, removes haze, and reveals the natural depth and dimensionality already present in the music.

Its advanced three-box architecture, higher Class A bias output stage, and carefully selected components create an exceptionally transparent and dynamic presentation. Quiet backgrounds become even darker, images gain stability and focus, and musical contrasts feel effortless and unconstrained—especially in highly revealing systems.

What makes the XS Pre 2 so compelling is how naturally everything flows. Music feels continuous and lifelike, with greater texture, scale, and emotional connection without sounding analytical or exaggerated. It’s the kind of component that quietly transforms an entire system by allowing every other piece to perform at its full potential.

Available in Silver or Black finishes.
