Pass Labs XS Pre-Amplifier

This large, dual-chassis preamplifier is built in true dual-mono arrangement. Each channel has its own power supply board with over 100,000uf of capacitance for unfettered transient response.

Noise levels have been dropped from the already low-noise XP30. Refined circuit design and layout, new gain-stages with auto-bias and DC compensation all combine for optimal performance.

It all comes down to sound; once you listen to the Xs preamplifier, there is no going back.
