Xs 300

Pass Labs Xs-300 Series Class A Mono Amplifier 

The Xs series monoblock power amplifiers represent the reference-quality, state-of-art amplifiers from Pass Laboratories. Through years of "spare no effort" endeavor, they represent the true pinnacle of music reproduction. The Xs 300 delivers 300 watts, employs separate power supply and amplifier chassis' for lower noise and utilizes higher-power constant-current source. Single-ended bias current not only lowers distortion, but facilitates better control of its harmonic structure, tweaked and optimized through endless listening tests for your musical pleasure.

Features

Class A Operation

The Xs 300 operates in Class A, providing a smooth, natural, and detailed sound signature

300 Watts per Channel

It delivers ample power to drive a wide variety of speakers, even those with demanding loads. 

Separate Chassis Design
