Orpheus Lab A Three S200 Power Amplifier

From $19,500

Swiss-engineered with six hand-matched MOSFETs per channel, this powerful stereo amplifier gives music a physical presence with breathtaking dynamics.

Discover the embodiment of musicality

The Absolute Amplifier transforms sound into a physical presence, giving music a body that you can feel as much as you hear. Every note takes shape, every chord gains weight, filling your space with a tangible energy.

The Absolute Amplifier redefines sound by giving it dimension and depth. Every detail is delivered with stunning precision, from the softest nuances to the most commanding crescendos. It transforms music into an immersive force, making every listening experience unforgettable.

The A Three S200 stereo amplifier from the Absolute line inherits the technology developed by Orpheus Lab for the Opus II of the prestigious Heritage line.

It features a current amplification stage driven by six high-power MOSFETs, meticulously hand-matched for each channel, capable of reaching instantaneous current peaks of up to fifteen amperes. To ensure optimal control throughout the amplification chain, each MOSFET is governed by a bipolar technology control stage. This approach, combined with a multi-point feedback topology, allows for the precise application of feedback, achieving a perfect balance between musicality and technical performance. As a result, the A Three S200 adapts seamlessly to any type of loudspeaker.

The Class AB architecture is brought to life by a carefully calibrated 125 mA bias current, delivering a thermal idle power of 15 WPC and allowing the amplifier, at rest, to stabilize at 15 °C above ambient temperature.

To guarantee flawless power delivery, each amplification channel is powered by an oversized toroidal transformer with a capacity of 880 VA.

The polarization circuit ensures optimal biasing regardless of the operating temperature. Furthermore, its low-impedance BJT component architecture maintains constant biasing irrespective of the load type, even at the highest current peaks.

Because musicality comes first and no measuring instrument can rival the human ear in this matter, these technological combinations have been meticulously refined through numerous iterations between laboratory measurements and listening sessions. The result is a purely musical experience, with breathtaking dynamic capability, extremely sharp note attacks, and exceptional openness.

Orpheus Lab is a Swiss electronics atelier that takes its name from the mythological poet whose music was said to move the world itself. That ambition is not accidental. Working from a tradition closer to fine watchmaking than conventional audio manufacturing, Orpheus Lab designs amplifiers and disc players with a philosophical clarity that reveals itself the moment music begins. The brand's digital foundations trace to Florian Cossy and Thierry Heeb, two engineers who came out of Goldmund, shaped the early architecture of Orpheus Lab's digital playback, and went on to found CH Precision. Their house sound is described as possessing an elegance and gracefulness — long on smooth, richly hued control — that makes music feel like a luxury. These are components designed not for those still chasing specifications, but for those who have arrived at a point where only the music itself matters.
