Product Description
The Rega Solis is Rega's flagship reference stereo power amplifier. Designed and hand-built in the UK, it is engineered to anchor top-tier audio systems, serving as the power house companion to preamplifiers like the Rega Mercury.
It represents a step up into absolute reference-grade power for Rega, blending massive current output with ultra-low distortion discrete topology.
Core Technical Architecture
-
Fully Symmetrical Topology: The Solis features a fully symmetrical discrete signal path throughout. Its voltage amplifier driver stage delivers high linearity and wide bandwidth, allowing the amp to manage severe dynamic swings without compressing.
- High-Current Output Stage: Uses 12 Sanken 130W 15A high-frequency multi-emitter output transistors (6 per channel) configured in a "triple" high-current stage. This allows it to maintain control and drive awkward speaker loads or low-impedance dips down to 4 ohms effortlessly.
- Dual Toroidal Power Supply: Inside are two low-noise 330 VA custom toroidal transformers with high-grade bonded cores. Paired with 40,000 µF of Rega K-Power smoothing capacitance per channel, it delivers raw transient speed and practically doubles power delivery as load impedance drops.
- Audiophile Components: Outfitted with Nichicon audio-grade capacitors, polyester bypass caps, and HTR non-inductive resistors in key positions to optimize high-frequency performance and low-end control.
