Audio Research S-200 Power Amplifier

With 200 watts per channel into 8 ohms and 400 watts into 4 ohms, the S-200 is designed to handle demanding, low-impedance speakers with ease. Its robust output stage provides the necessary headroom to maintain composure and dynamic control even with complex, power-hungry speaker loads.

Yes, the S-200 features switchable inputs, allowing you to use either balanced XLR or single-ended RCA connections. This flexibility ensures compatibility with a wide range of preamplifiers and source components.

The fully balanced signal path helps reject common-mode noise and interference, resulting in a cleaner, quieter background. This architecture preserves the integrity of the audio signal from input to output, which contributes to the amplifier's overall clarity and tonal purity.

The differential JFET input stage is chosen for its low-distortion characteristics and high input impedance. It helps the amplifier maintain a delicate, nuanced sound, ensuring that subtle details in your recordings are preserved without adding harshness or coloration.

Beyond their aesthetic appeal, the dual power meters provide real-time visual monitoring of your output levels. They offer a helpful reference for how hard the amplifier is working during dynamic musical passages.

While the S-200 features custom-machined heatsinks designed for optimal thermal stability, it is a high-performance power amplifier that generates heat during operation. We recommend placing it in a well-ventilated area with sufficient clearance around the chassis to ensure longevity and consistent performance.
