Pass Labs Xs Pre 2 Preamplifier

The fully redesigned three-box Pass LabsXS Pre 2 incorporates innovations from the ground up. 

Sonically, it is quieter and more dynamic than its predecessor, with better resolution from the new power supply and gain circuitry. It recreates space more accurately for improved realism thanks to upgrades in both the gain stage and the supply.

The power supply is dual mono with three double-shielded transformers - one per channel plus a separate digital supply, along with increased capacitance and added pre-regulators. The output stage runs with more Class A bias and lower output impedance, making it easy to drive long cable runs and any power amplifier, while the volume control offers 100 dB of range in 0.5 dB steps.

New ceramic-based, gold-plated circuit boards feature Toshiba FETs in the input stage and MOSFETs in the output stage - parts Pass Labs have long preferred for maximum sonics and secured for product longevity. The new chassis is furnished with dual organic LED type displays. 

Product Features

Dual-Mono, Three-Chassis Design

Each channel has its own power supply and circuit boards, and the power supply is also dual-mono with three double-shielded transformers

New Gain Circuit

The gain circuit features higher bias, better stability, and lower noise, resulting in improved resolution and dynamics

Toshiba FETs and MOSFETs

The input stage uses Toshiba FETs, and the output stage uses Toshiba MOSFETs. 

Class A Bias and Lower Output Impedance

The output stage runs a higher class A bias, has auto-bias, and has lower output impedance, allowing it to drive long cable runs and various power amplifier
