BRAND: Pass Labs

SERIES: Xs300 Power amplifiers
TYPE: Power Amplifier

Pass Laboratories, Inc. was founded in 1991 by Nelson Pass.  Operating out of his shop at home, Pass developed prototypes of a single-ended Class A amplifier design.  At the same time, he and Mike Burley were constructing an in-house machine shop with three home-built CNC milling machines with which to produce the amplifiers when the design was finished.

 

OVERVIEW

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.
