Rega Osiris Integrated Amplifier

Rega Osiris Integrated Amplifier A super high performance, 162 Watts into 8 Ohms (250 Watt 4 Ohms) dual mono amplifier housed in a custom Rega CNC machined aluminium case with high thermal efficiency heat sinks. Designed around "minimalist" high gain power amplifier and "passive pre-amplifier" circuit topology, a passive volume control and a single stage of power amplification between the input and the speakers the Osiris offers unrivalled performance and build quality. Technology The Osiris uses a low distortion high linearity and bandwidth common base voltage amplifier driver stage. This type of symmetrical circuit topology will provide the necessary voltage swings to enable the Osiris to drive any speaker system with the minimum of distortion. Eight Sanken 200 Watt output transistors are used in a "triple" high current output stage enabling the Osiris to drive even the most awkward of speaker systems with ease. The cascoded differential input amplifier uses two low noise LED referen
