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. They measure well and sound great. They are heavy, reliable and expensive.
Awards and Reviews
"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." Jack Roberts

"Its divine transparency blesses and illuminates every aspect of the music it touches, enhancing the subtlest aspects of tone, texture, microdynamics, space, and atmosphere."
"I thought I would never hear a solid-state amplifier that could create the gorgeous timbres/tonality/color of the finest tube-based amplifiers, yet that's what you get with the XA25"
"With my audiophile ears standing at full attention I noted that each instrument sounds like it's in its own "space" on my favorite recordings."
