PASS LABS PHONO PREAMPS
SOLID STATE CLASS A PHONO STAGE PREAMPLIFIERS
"Exceptional resolution and dynamics. Stringed instruments sounded divine with richness and fullness, not just details only for the sake of details–the natural timbre of those strings played the prominent role; they were brought to life. Exquisite."

XS Phono Preamplifier
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
The twin chassis XP-27 delivers enhanced RIAA performance at a fraction of the previous distortion standards. The power supply is dual mono with two transformers with lower radiated and mechanical noise. Noise is the most prominent part of THD+N at low levels, so by lowering noise we get better resolution and dynamics.The XP-27 input and gain circuitry are similar to that found in the Xs Phono. This means switching and loading is done at higher signal levels, minimizing noise and improving low level performance.
XP17 uses the new-shielded low noise toroid and input filter module. The power supply has an extra stage of RC filtering with lower radiated and mechanical noise. It has an all-new input circuit that is symmetrical and lower in noise and distortion with greater drive capability. Noise is the most prominent part of THD+N. By lowering noise we get better resolution and dynamics. Designed with a split EQ network like the XS Phono that is more accurate and can handle greater signal levels. The secondary stage runs a higher bias output stage with auto bias.
Numerous loading options are available, as are three gain settings to accommodate low output MC to MM cartridges.
