Meet the apex of Class A

When the Xs 300 monoblocks meet the Xs Pre 2 preamplifier, music transcends playback—it becomes an experience.

The Xs 300 delivers 300 watts of fearless, pure Class A power, sculpting sound with grip, scale, and tonal richness that feels alive.

Effortless at the quietest passages, limitless at concert peaks—this is control and color in perfect harmony.
Pair that with the Xs Pre 2—a three-chassis masterpiece Wayne Colburn calls “the best work I’ve done in 35 years.” With its ultra-quiet power supply, refined Class A gain stages, and precision volume control, the Xs Pre 2 unlocks breathtaking realism, layering music with nuance, space, and flow.

Together, they redefine what’s possible in home audio.

Scale. Texture. Space. Emotion.
A system that keeps you listening long after the lights go down.
