Rega Solis – Reference Stereo Power Amplifier with 305 W Performance
The Rega Solis is a no-compromise stereo power amplifier designed to deliver absolute control, scale, and musical authority. Hand-built in England and engineered to partner perfectly with the Rega Mercury pre-amplifier, Solis combines fully symmetrical discrete circuitry with immense current delivery to drive even the most demanding loudspeakers with ease—available at Soundium.
Key Features
-
Fully symmetrical discrete signal path: Differential architecture designed for low distortion, wide bandwidth, and maximum transparency
-
High-power output stage: Delivers 168 W per channel into 8 Ω and 305 W per channel into 4 Ω
-
Balanced and unbalanced inputs: Flexible integration with high-end pre-amplifiers and sources
-
Triple high-current output stage: Uses twelve Sanken 130 W output transistors for exceptional speaker control
-
Advanced protection systems: Short-circuit, thermal cut-out, and DC protection ensure safe long-term operation
-
User-selectable standby and mute: Includes independent mute function and 12 V trigger support
Customer Benefits
The Solis is built for listeners who demand effortless dynamics, deep low-frequency grip, and unwavering stability at high listening levels. Separating the power amplification from the pre-amplifier reduces noise and interference, resulting in a cleaner signal path and a more open, controlled soundstage. Whether paired with reference bookshelf speakers or large floorstanders, Solis delivers authority without sacrificing refinement.
