Pass Labs XA25

A25 Watt Pure Class A Stereo Power Amplifier.


The Pass Labs XA25 Stereo Power Amplifier is "a simple 3 stage circuit with total of three pair of push-pull gain transistors. In their ideal state, matched push-pull FETs give perfect 'square law' cancellation of distortion, an effect somewhat spoiled by degenerative Source resistance used to constrain the 'personality' of the devices. The removal of this form of feedback is an important element in the performance of the XA25 and is accomplished by new approaches to stabilizing gain and bias of push-pull FETs."

The Passlabs XA25 goes from light blue to dark blue and all the shades in between instead of just the color blue. The singers' timbres sound like in real life.  It brings out the unique characters in their voices.  The X25 also delivers a potent transparency as if the audio system had disappeared, making possible a direct view of what the microphones registered, unmitigated.
