Xs Phono

Xs Phono

The Xs Phono preamplifier represents an all-out assault on the state-of-art in Vinyl and the most intensive and difficult design effort made at Pass Laboratories. The final product of this massive effort extracts the utmost performance from a simple topology  and operates with the extremely small and delicate signals coming from today's wide variety of phono cartridges. The result is music that emerges from a quieter background and blooms into a richer, more precise soundstage.
