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
The X260.8 is a refined musical instrument delivering 260 watts into 8 ohms, and combines power and finesse with all the benefits of mono-block performance. Its measured performance – distortion, bandwidth, noise, and resolution is beyond reproach. Like all of the class A/B .8’s, this amplifier has some class A bias, rewarding its listeners with a whole new zenith of sound quality.
