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.

Who is this for?

The Rega Solis Stereo Power Amplifier is designed for experienced audiophiles building a true reference-level two-channel system. It suits listeners who already own a high-quality preamplifier and source components, and who want a power amplifier capable of delivering absolute control, scale, and musical realism without sacrificing refinement.

Unlike amplifiers that focus purely on brute force, the Solis is aimed at listeners who value musical realism and emotional engagement just as much as technical performance. It combines immense authority with fluidity and composure, allowing recordings to sound expansive and effortless rather than aggressive or clinical.

The Solis is intended for carefully matched setups where every component has been chosen for long-term performance. Pair it with a quality analogue front end, premium DAC, or high-end streamer, and the Solis reveals just how much scale, texture, and spatial depth great recordings can contain.

What is the Rega Solis Stereo Power Amplifier designed to do?

The Rega Solis is Rega's flagship stereo power amplifier, designed to deliver reference-level performance with exceptional transparency, control, and musicality. It is engineered to partner with high-end preamplifiers and source components in serious audiophile systems.

Is the Rega Solis a power amplifier or an integrated amplifier?

The Solis is a dedicated stereo power amplifier. It does not include volume control, source selection, or streaming capabilities, and must be used with a separate preamplifier such as the Rega Aura, Rega reference electronics, or other high-quality preamps.

What makes the Rega Solis different from conventional power amplifiers?

The Solis has been designed with a focus on low distortion, high current delivery, and exceptional musical engagement. Its fully balanced architecture and carefully engineered power supply allow it to reproduce music with remarkable precision and authority.

How much power does the Rega Solis deliver?

The Solis provides substantial power reserves and high current capability, allowing it to drive a wide range of loudspeakers with confidence while maintaining control during demanding musical passages.

Is the Rega Solis suitable for difficult-to-drive speakers?

Yes. The amplifier is designed to remain stable under challenging loads and can drive many high-end loudspeakers that require significant current delivery and control.

What type of sound does the Rega Solis produce?

The Solis is designed to deliver a natural, transparent, and highly dynamic presentation. It combines excellent detail retrieval with strong bass control and a realistic sense of scale and musical flow.

Does the Solis support balanced connections?

Yes. The amplifier includes balanced XLR inputs, allowing it to be partnered with high-quality balanced preamplifiers for optimal performance and noise rejection.

Can the Rega Solis be used in a reference-level system?

Absolutely. The Solis was developed specifically for high-end and reference-level audio systems where maximum performance and long-term ownership are priorities.

What type of speakers pair well with the Solis?

The amplifier works exceptionally well with premium bookshelf and floorstanding speakers, particularly those capable of revealing the amplifier's resolution, dynamics, and control.

How does the Solis compare to integrated amplifiers?

A dedicated power amplifier like the Solis allows designers to focus entirely on amplification performance. When paired with a high-quality preamplifier, it can offer greater power reserves, refinement, and system flexibility than many integrated designs.

Is the Solis designed for both analogue and digital systems?

Yes. Because it is a power amplifier, it can be used with any source chain, including turntables, streamers, DACs, CD players, and modern digital music systems, provided a suitable preamplifier is used.

Can the Solis be part of a future upgrade path?

Yes. As a reference-grade power amplifier, it is designed to remain at the heart of a system through future upgrades to source components, preamplifiers, and loudspeakers.

What type of music benefits most from the Solis?

The Solis excels across all musical genres. Its combination of control, transparency, and dynamic capability makes it equally impressive with orchestral works, jazz ensembles, rock recordings, and intimate vocal performances.
