Product Description
The Rega Osiris is Rega's flagship, no-compromise integrated amplifier. Positioned at the top of their Reference range alongside the Isis CD player and Aura phono stage, it is built with an extreme focus on power delivery, minimalist signal paths, and massive, rigid chassis construction.
Core Architecture & Design Philosophy
-
Minimalist Dual-Mono Topology: The Osiris functions around a high-gain power amplifier topology combined with a passive pre-amplifier section. There is effectively only a passive volume control and a single stage of power amplification between input and output.
- Massive Power Supplies: It features two custom, low-noise 400VA toroidal transformers feeding separate audio circuits for each channel. Coupled with 40,000 µF of Rega K-Power smoothing capacitors per channel, it guarantees massive headroom and stability under challenging speaker loads.
- High-Current Output: Uses eight Sanken 200 Watt output transistors in a triple high-current output configuration, giving it effortless grip over demanding speaker impedance dips.
- Isolated Control Systems: The microcontrollers, input switching relays, and protection circuits are completely isolated with their own dedicated power supply to prevent digital and switching noise from entering the signal path.
