Sound Advice

Next level performance

Engineered to drive the most demanding of speakers, the Solis is the perfect partner for the Mercury Pre-amplifier. Our engineering team have spent the last four years obsessively developing and fine tuning the circuit to create the most engaging and accurate performance. The advantage of using a separate chassis for the pre-amplifier and power amplifier allows the low voltage, sensitive circuitry to be isolated from the high current, power amplifier circuitry. This reduces interference between the pre-amplifier and power amplifier leading to a less noisy signal path and a cleaner signal. Also compatible with the Rega Aethos stereo power amplifier.

High-Power Amplification

The Solis features fully symmetrical discrete circuitry throughout the signal path and offers both balanced and unbalanced inputs for flexible system integration. Delivering an impressive 168W into 8Ω and 305W into 4Ω, it provides powerful, controlled performance with built-in short-circuit protection, thermal cut-out, and DC protection for long-term reliability. A user-selectable standby mode and 12V trigger make it easy to integrate into automated setups, while an independent mute function adds further convenience. Designed to partner seamlessly with the Mercury pre-amplifier and the Aethos stereo amplifier, it forms the foundation of a refined and highly capable audio system.

The Solis features two custom-designed, low-noise 330VA toroidal transformers made with high-grade bonded core material, which reduces mechanical noise even under challenging mains conditions. Combined with 40,000µF of Rega K-Power smoothing capacitors per channel, these transformers deliver ample current to handle demanding speaker loads, effectively doubling power into 4Ω compared to 8Ω. Fast recovery rectifier diodes are used throughout the power supplies, reducing high-frequency switching noise for cleaner DC. The input and low-level driver stages receive power from a regulated symmetrical tracking supply with a low-noise voltage reference, ensuring stable, ultra-clean voltage for the highest sonic purity. All dedicated audio power supplies are reserved solely for the audio circuits.

A question of balance

For most home Hi-Fi systems, unbalanced connections deliver the best sound quality, and this is what the Mercury and Solis are designed around. While balanced circuits are standard in professional studios—helping cancel noise over long cable runs—they don’t inherently improve the listening experience for domestic systems.

Rega’s approach focuses on pure performance: the core circuitry is unbalanced, keeping the signal path clean and free from unnecessary complexity. Balanced XLR connections are included for those who need them, such as studio applications, or simply prefer the professional feel of premium connectors. While these offer convenience and versatility, the true sonic performance comes from the carefully engineered unbalanced design at the heart of the Mercury and Solis.

In short, Rega delivers uncompromised audio clarity, whether you stick with standard unbalanced connections or take advantage of balanced options for specific setups. Every detail is optimized to ensure the purest, most natural sound in your home system.

The Mercury and Solis combine staggering performance with real world forgiveness in a way that makes it look easy when it really, really isn’t.

In the end, it didn’t matter what genre I threw at the Rega stack. From raucous rock to grand operatic productions, the Mercury and Solis never sounded overwhelmed or out of their element.

The Mercury/Solis combination punches way above its price and anyone looking for serious amplification with a lifetime guarantee put aside their prejudices and compare it with the best in class.
