The ultimate Rega integrated amplifier — absolute authority, zero distraction
Rega Osiris Product Introduction
The Rega Osiris Reference is the most ambitious integrated amplifier Rega has ever designed.
It exists to answer a very specific question: how far can an integrated amplifier be pushed before separates become unavoidable?
The answer, in the case of the Osiris, is remarkably far.
At Authentic High End, the Osiris Reference is positioned as a true endgame amplifier — for listeners who want maximum authority and control, without fragmenting their system into multiple boxes.
Positioning Within Rega
The Osiris Reference sits:
at the absolute top of Rega’s integrated amplifier range,
above the Aethos,
just below Rega’s reference separates (Mercury & Solis).
It is designed for:
reference-level loudspeakers
large listening rooms
systems where the amplifier must never be the limiting factor
listeners who want ultimate performance in a single chassis
Design Philosophy: Power, Stability and Musical Truth
Rega designed the Osiris with no interest in feature count and complete focus on amplification quality.
Core principles include:
a fully discrete analogue signal path
massive linear power supply with exceptional current reserves
ultra-short signal routing
extreme mechanical rigidity and grounding discipline
There is no DAC, no phono stage and no digital processing. Every resource is devoted to pure amplification.
Extreme Current Delivery & Loudspeaker Control
The Osiris Reference is engineered to deliver extraordinary current capability, allowing it to:
remain stable into complex loudspeaker loads
control bass drivers with absolute authority
remain composed during extreme dynamic swings
Rather than sounding forceful or aggressive, the Osiris delivers power with calm inevitability.
Listening Experience
The Rega Osiris Reference sounds:
Music expands in scale without losing focus. Timing remains intact, even during dense passages, and the amplifier never draws attention to itself — it simply gets out of the way.
Build Quality & Everyday Use
Despite its reference ambitions, the Osiris remains a practical amplifier:
heavy-gauge aluminium chassis
understated, purposeful design
reference-grade control interfaces
supplied reference remote handset
It is built for decades of daily use, not occasional admiration.
System Integration
The Osiris Reference is designed for no-compromise systems:
ideal partner for external reference phono stages and DACs
perfect match with Rega Planar 8, Planar 10 and Naia
suitable for the most demanding loudspeakers
At Authentic High End, the Osiris is typically demonstrated in systems where everything else is already resolved, and the amplifier must simply deliver.
Why We Selected the Osiris Reference at Authentic High End
We selected the Osiris because it demonstrates something rare:
an integrated amplifier that does not feel like a compromise.
It offers:
For listeners who want the best Rega can do in a single box, the Osiris Reference is the destination.
