Rega Solis Stereo Power Amplifier

Solis is a high-performance power amplifier built to deliver effortless control, speed, and musical authority. Designed as the perfect partner to the Mercury preamplifier, Solis brings Rega’s engineering philosophy to the output stage—prioritizing low distortion, high current delivery, and absolute signal integrity.

From the moment it’s powered on, Solis demonstrates a commanding sense of grip and composure. It drives speakers with confidence and precision, maintaining clarity through complex passages while preserving the natural dynamics and rhythm of the music. Whether paired with demanding floorstanders or more revealing monitor designs, it delivers a presentation that is both powerful and refined.

At its core, Solis uses a fully discrete amplifier design supported by a robust, carefully engineered power supply. The result is a wide, stable soundstage, excellent bass control, and a sense of effortlessness that allows music to breathe. It never feels forced—just controlled, articulate, and deeply engaging.

Finished in Rega’s understated aluminium enclosure, Solis reflects the same design principles as Mercury: simplicity, rigidity, and performance-first engineering. Together, they form a cohesive, reference-level separates system designed for listeners who want to experience their music without compromise.
