Balanced Output
Bridgeable

The X150.8 is all about balance: speed and sweetness, punch and finesse. It brings the grip and dynamic confidence of Class AB while preserving the tonal honesty and low-level nuance Pass Labs is known for.



It’s a powerful, highly musical stereo amplifier that works beautifully across a wide range of speakers—especially when you want authority without giving up texture.


The character is confident but never sharp: transients are clean, bass is controlled, and the midrange stays richly communicative. The X150.8 is a strong foundation for real-world systems because it plays to music first—making your speakers sound more composed, more dimensional, and more enjoyable at any volume.
