Aethos integrated amplifier from Rega

This new design delivers 125W per channel into 8 Ohms. The Aethos is a dual mono design using a custom wound toroidal transformer and regulated supplies

The pre-amplifier stage uses class-A circuitry throughout.

A switchable direct input and preamplifier output, enables the new Aethos amplifier to be used in a wide combination of systems.

This is a fully discrete FET based line amplifier with polypropylene capacitors.

You’ll also find K-Power reservoir capacitors, power amplifier regulated supply and a high current output stage.

It comprises of four 160W Sanken output transistors per channel.

The Aethos uses a combined feedback and passive volume control plus line amplifier.

This was originally developed for the Elex-R.

The power amplifier used in the Aethos is an improved higher power version of the power amplifier used in the Elicit-R and Elex-R.

It is based around two complementary pairs of 160W Sanken Darlington output transistors. 

By combining the low impedance driver with the Sanken Darlington transistors (with their imbedded thermal bias network running at a lower standing current), this combination forms a complementary emitter follower emulating Class-A conditions.

Two complete output stages are run in parallel, this includes the output transistors, bias network and pre-diver transistor. 

Spanning 433 x 95 x 360, it weighs 17.5kg.

The price is £2,999.
