Product Summary

The Rega Osiris is Rega’s flagship integrated amplifier, created for customers who want true reference-level performance without moving to separate pre and power amplifiers.

It is a no-compromise design built for serious two-channel systems, combining huge power with the kind of control, refinement and musical authority expected from a statement amplifier.

A big part of the Osiris appeal is the way it keeps the signal path deliberately simple while still delivering enormous drive capability.

Rega uses a dual mono layout, passive preamplifier topology and a single stage of power amplification between the input and the speakers, helping the Osiris sound exceptionally direct, controlled and expressive.

That makes it especially attractive for customers partnering ambitious loudspeakers and high-end sources.

The Osiris is also designed to feel every bit like the flagship it is. Its custom CNC-machined aluminium casework, reference remote handset and massive power supply all reinforce the sense that this is a genuinely serious long-term amplifier.

For customers wanting a true end-point integrated amplifier with huge power and exceptional build quality, the Rega Osiris is a very compelling choice.
