Xs Series

Class A

These are Pass Laboratories ultimate expression of Power Amplifiers the perfect blend of science and visceral emotion.

If there’s a more emotionally satisfying amplifier anywhere, we’re not aware of it.

The successor to our already lavishly praised and well regarded Supersymmetry patent. Every technical effort has been made to assure exceptional specifications, among these:

Separate chassis 
for lower electromagnetic noise

Power supplies 
with greatly enhanced storage capacitance

Banks of redundantly parallel high speed 
and soft recovery rectifiers

Noise filters 
with improved high frequency

Larger and quieter transformers

Improved passive decoupling

Lower power standby

Input impedances
of 200 k-ohm balanced with negligible capacitance
