The Elysian Stereo 100 Power Amplifier

The Elysian Stereo 100 Power Amplifier

A compact stereo power amplifier capable of driving any loudspeaker and designed to outperform larger amplifiers while fitting perfectly into your listening room.

The Elysian Stereo 100 (ES100) can operate as a stereo amplifier delivering 100W into 8ohms or it can operate as a bridged mono-block amplifier delivering 350W into 8ohm and offering the perfect upgrade route.

The ES100 houses two true state of the art, ZERO global & ZERO local feedback, wide bandwidth, Class A amplifier circuits, thus producing the most dynamic, transparent and realistic sound stage possible.

Coupled Symmetric Drive "CSD"

CSD topology allows bespoke zero feedback circuits to operate at high speed with very low distortion levels.

The CSD input stage consists of a fully balanced symmetrical differential stage with a small voltage gain using ultra high linearity complementary transistor pairs, operating in class A mode with NO feedback. This stage drives a balanced symmetrical push pull voltage amplifier stage again operating in class A mode with NO feedback and a moderate voltage gain.

CSD is essentially two true zero feedback amplifiers operating in parallel to increase bandwidth and reduce THD, IMD and TIM.

Optimum Bias "OpBias"

Optimum Bias "OpBias"

At normal listening levels the ES100 will operate in Class A mode and deliver up to 5 watts of pure Class A power. If extra power is required the ES100 will seamlessly move into Class A/B operation and deliver over 100W into 8ohms (stereo) and 200W into 4ohms (stereo) or 350W into 8ohms (mono). This biasing technique results in lower power consumption, lower heat output and an extended component lifetime over that of a conventional Class A amplifier, while delivering superior performance.
