If you are looking for a Pure Class A, Valve Masterclass – the Genus 845 Integrated is for you.
With a footprint of 520mm x 530mm, Genus is the most compact design to date, yet remains faithful to the no compromise approach.
The Genus integrated is 25W in Class A1 yet only has two gain stages.
It is effectively a small stereo SET amplifier driving a bigger stereo SET in one chassis.
All four tubes have independent power supply units (PSUs) which are fed from dual 400V toroid transformers,800VA total.
All four PSUs carry their own choke filtered capacitor bank.
The input / driver stage is a small 0.7W SE amplifier built around the Siemens E280F super triode and is loaded with a double c-core bifilar wound interstage transformer.
This single tube stage offers maximum linearity and bandwidth for maximum transparency.
No coupling capacitors are present anywhere in the circuit.
The small SE amplifier uses our proprietary AC link coupling technology to link to the output stage.
For output stage, two 845 directly heated triode (DHT) tubes are used.
Aries Cerat passive filter system is fault proof and provides an extremely low noise floor with very high bandwidth and non-feedback design.
Bias of all four tubes,both the two the driver and two output tubes can be adjusted on the fly using the built-in bias meter, so you can tailor the sound to your taste,but also monitor tube’s current long term.
A self resetting soft start is used to slowly build up the high voltages present and protect the tubes from any current surges at start up.
Aries Cerat Genus (845 valve) is available for demo at Centre Circle Audio showroom.
