S-200 Solid State Power Amplifier By Audio Research

The S-100 and S-200 amplifiers represent a sophisticated approach to modern solid-state amplification, combining powerful performance with refined engineering and elegant industrial design.

The S-200 features a pure Class A/B architecture supported by robust linear power supplies and a true dual-mono layout. Dual toroidal transformers power fully balanced stereo circuits, delivering exceptional channel separation, dynamic authority, and musical precision.

Bipolar transistors were selected for their transparency, speed, and natural sonic character, offering impressive clarity and dynamic realism throughout the listening experience.

Crafted with a precision-machined aluminum chassis available in black or silver anodized finishes, the S-Series blends classic Audio Research styling with a cleaner, more contemporary aesthetic. Custom-machined heat sinks and hidden fasteners create a sleek, uninterrupted appearance from every angle.

The S-200 also incorporates elegant front-panel power output meters inspired by modern ARC meter designs, set against a striking black background for a distinctive visual presentation.

Each amplifier undergoes extensive testing and careful listening evaluation to help ensure exceptional build quality and musical performance. Whether the S-100 or the S-200 is the better match for your system will depend on your speakers; Jaguar can help you figure this out.

“Looking for maximum impact amplifiers, with the excitement dialled up to 11, you won’t go far wrong here. The no-frills approach, flexibility of the LS-2 with those plug-in options, massive power of the S-200 and the purposeful styling will also all appeal. But there’s a nagging doubt that these amps sometimes try too hard, meaning care with partnering components may be needed to tame them a little.”
