Pass Labs XA25 Amplifier
Entering their 22nd year of production, the X and XA power amplifiers have remained at the cutting edge of audio through continuous innovation and refinement. At Pass we build amplifiers with excessive output stages, huge heat sinks and massive power supplies. We use the highest quality components in simple linear topologies, assembled and tested with great care in Auburn, California. The measure well and sound great. They are heavy, reliable and expensive.
