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.
