The XA25 measures superbly, but its subjective qualities are most special. In an industry where products with great specs are frequently found to be dry and boring, this amplifier breathes life into the music.
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 they build amplifiers with excessive output stages, huge heat sinks and massive power supplies. Using the highest quality components in simple linear topologies, assembled and tested with great care in Auburn, California. They measure well and sound great. They are heavy, reliable and expensive.
The new XA25 offers this at slightly lower power, without frills, at a lower price. It embodies new components and innovative circuits coupled with the best elements of the previous generation.

As I listened to album after album, I could hear the textures, colors, tones, and harmonics of music in a way that was very moving. The system’s timbre realism with individual instruments and voices was as satisfying with the XA25 as it had been with any amp. All of this added up to enable my system to play music with a wonderful lifelike flow."
