Brief Description

The Elysian 100 series mono-block amplifier is a statement in audio design, an elegantly

minimalist, aesthetically pleasing mono-block power amplifier housing a true state of the art, ZERO

global and ZERO local feedback, ultra wide bandwidth, Class A operating amplifier circuit.

The Elysian 100 incorporates CAAS Audio's proprietary short signal path, minimal component, two

stage, DC coupled, voltage gain topology "CSD" (Coupled Symmetric Drive). The Elysian 100 uses

a fully symmetric DC coupled design from the input right through to the output. By taking

advantage of the higher bandwidth, speed and lower distortion offered by a two stage fully

symmetric topology, a true zero feedback system can be employed thus producing one of the most

dynamic, open, transparent and realistic sound you'll ever hear.

The Elysian 100's voltage amplifier circuit is based on CAAS Audio's "CSD" topology. The input

stage consists of a fully balanced symmetrical differential stage with a small voltage gain using

ultra high linearity complimentary transistor pairs, operating in class A mode with NO feedback

except emitter degeneration. This stage drives a balanced symmetrical push pull voltage amplifier

stage again operated in class A mode with NO feedback and a moderate voltage gain. Input stage

current sources are coupled and our proprietary non-intrusive DC servo circuit which continuously

fine tunes these current sources (at an ultra low sub sonic frequency) to maintain a very low DC

output level.

The Elysian 100's output stage consists of a bespoke Voltage amplifier Perfect Isolating "VPI"

driver stage driving five complementary pairs of high bandwidth transistors biased heavily towards

Class A and running open loop (NO feedback). At normal listening levels the Elysian 100 will

always be running in Class A mode. In fact the Elysian100 will deliver over 20 watts of pure Class

A power into an 8 ohm load. If extra power is required the Elysian 100 will seamlessly move into

Class A/B operation and deliver over 100W into 8 ohms and 200W into 4 ohms.

This biasing technique results in lower power consumption, lower heat output and an extended

component life time over that of a conventional Class A amplifier, while delivering superior

performance.

Each Elysian 100 houses six separate power supplies. Each Channel has six independent

bespoke discrete regulated, very high speed, very low output impedance, high current delivery

power supplies. Four for the voltage amplifier stages and two for the current amplifier output stage.

Six years of R&D coupled with novel circuit topologies, the most linear components available, an

attention to detail and a no compromise philosophy has culminated with The Elysian 100 and a

giant leap forward in audio reproduction.
