PASS LABS XS PRE 2 + XS 300: BUILT TO VANISH


The Pass Labs Xs Pre 2 is built to vanish. It’s not about “preamp sound”—it’s about removing haze, lowering noise, and recreating space with such precision that recordings feel physically believable.


With a fully rethought three-box architecture, higher Class A bias in the output stage, and meticulous parts choices, the Xs Pre 2 delivers effortless dynamics and extraordinary realism—especially in resolving systems.

The result is a sense of continuousness: backgrounds go darker, images gain stability, and the system’s dynamic contrasts feel more natural and uncompressed. It’s the kind of component that doesn’t call attention to itself—until you realize how much more music your system is now delivering, track after track.


SPECS AT A GLANCE

Gain: 10.5 dB (Balanced)
Output impedance: 30 Ω (RCA), 60 Ω (XLR)
Input impedance: 20 kΩ (RCA), 40 kΩ (XLR)
Residual noise: <15 μV | THD: ≤0.001% @ 1 V, 1 kHz

The Xs 300 is the kind of amplifier that makes “state of the art” feel like a real thing. It delivers startling realism at any level—micro-detail, dynamics, tonal density, and scale—without ever sounding forced.


This is reference Class A power with the finesse to disappear completely. When the amplifier stops being a component and becomes simply the music, you’re in Xs territory.
It’s also a masterclass in control: bass arrives with authority and shape, images hold steady through big swings, and the stage remains expansive and organized. If your system is revealing and your speakers can take advantage of true Class A headroom, the Xs 300 is the kind of endgame that keeps getting better as the rest of the chain improves.
