Product Highlights

The Pass Labs X350.5 power amplifier delivers 350 watts per channel into 8 ohms (700 watts into 4 ohms) and a 28-amp maximum output. This high-power stereo amplifier utilizes a two-stage topology with a balanced Class A input stage and matched MOSFET output devices. Featuring patented Supersymmetry circuit design, it cancels noise by perfectly aligning both halves of the balanced circuit. It runs under heavy bias, operating in pure Class A for the first 40 watts before moving into Class AB. It is housed in a rugged chassis with a distinct glowing blue meter.

Acclaimed by critical reviewers at The Absolute Sound and Audioholics, the X350.5 is praised for its exceptional neutrality and lack of coloration. Experts highlight how it pairs the liquid, grain-free midrange warmth of a tube amplifier with the iron-fisted bass control, speed, and grip of elite solid-state gear. Reviewers consistently note its expansive soundstage and its ability to drive notoriously difficult, power-hungry speaker loads with absolute ease and zero listener fatigue.

Bringing an unparalleled blend of muscular authority and delicate realism to your listening room, this component elevates any high-end audio system. It breathes lifelike energy into complex recordings, resolving micro-details against a perfectly quiet background. Adding this definitive powerhouse to your setup removes all limitations on speaker pairings and dynamic strain, inviting you to stop evaluating the equipment and simply immerse yourself in the pure emotion of music.
