Rega Solis

Unlimited power, absolute control — amplification without constraint

Rega Solis Product Introduction

The Rega Solis Reference represents the final stage of Rega’s no-compromise reference amplification system.
Designed to be partnered with the Rega Mercury Reference preamplifier, Solis exists to do one thing perfectly: convert a pristine line-level signal into effortless, unlimited loudspeaker control.

Solis does not aim to impress through specification excess or visual drama. Its ambition is far more demanding — to deliver absolute authority while remaining musically invisible.

At Authentic High End, Solis is positioned for listeners who want amplification that never imposes itself on the music, regardless of scale or complexity.

Positioning Within Rega

The Solis Reference sits:

• at the absolute top of Rega’s power amplifier range,

• above all integrated amplifiers,

• as the natural partner to Mercury Reference.

It is designed for:

• reference-level loudspeakers

• large listening rooms

• systems where current delivery and stability are non-negotiable

• listeners who want the performance of separates without compromise

Each Solis is a true mono power amplifier, ensuring total channel separation and maximum control.

Design Philosophy: Current, Stability and Timing

Rega’s design brief for Solis was uncompromising:

the amplifier must never run out of control, current or composure.

Core principles include:

• fully discrete analogue amplification

• extreme current reserves

• ultra-short signal paths

• exceptional mechanical rigidity and grounding discipline

There is no feature circuitry of any kind — no DAC, no phono stage, no switching complexity. Everything exists to serve pure amplification.

Mono Architecture: Why It Matters

By using separate mono power amplifiers, Solis achieves:

• complete electrical separation between channels

• improved imaging stability

• greater dynamic headroom

• superior control of complex loudspeaker loads

This architecture allows music to scale naturally, without congestion or compression.

Listening Experience

The Rega Solis Reference sounds:

• limitless in dynamic range

• utterly controlled in the bass

• rhythmically exact

• calm and authoritative under all conditions

Even during demanding orchestral peaks or high-energy electronic music, Solis remains unflustered, allowing the music to unfold with realism and intent.

Build Quality & Longevity

Solis is engineered for long-term reference use:

• heavy-gauge aluminium chassis

• extremely rigid internal construction

• robust thermal management

• designed and built in England

It is built as a lifetime amplifier, not a product cycle.

System Integration

The Solis Reference is intended for no-compromise systems:

• perfect partner for Rega Mercury Reference

• ideal match with Rega Planar 10 and Naia

• suitable for the most demanding loudspeakers on the market

At Authentic High End, Solis is demonstrated only in systems where the entire signal chain is resolved to reference level.

Why We Selected Solis Reference at Authentic High End

We selected the Solis Reference because it represents Rega’s ultimate amplification belief:

• power must never dictate sound

• control must never suppress emotion

• authority must never become aggression

Solis does not impress by shouting. It convinces by never being the problem.
