{"product_id":"s-200-stereo-power-amplifier","title":"S-200 Stereo Power Amplifier","description":"\u003cp\u003eThe S-200 is Audio Research's most advanced solid-state stereo power amplifier, a pure Class A\/B design built on a true dual-mono platform. Dual toroidal transformers feed fully balanced circuits, and the choice of bipolar output transistors reflects a deliberate engineering priority: purity, transparency, and dynamic agility over the softer presentation often associated with MOSFET designs. A muscular linear power supply ensures the amplifier maintains composure and authority even as impedance demands shift.\u003c\/p\u003e\n\u003cp\u003eHoused in a beautifully machined aluminum chassis available in black or silver anodized finish, the S-200 nods to classic Audio Research design language from a sleeker, modern perspective. Custom-machined heat sinks and the absence of visible fasteners on the front and top panels contribute to a refined, understated presence. Power output meters on a solid black background provide a visual connection to the amplifier's operation, and like every Audio Research product, the S-200 is proofed by ear in the company's Minnesota facility before it leaves the factory.\u003c\/p\u003e\n\u003ctable class=\"pu-table\" style=\"width:100%;border-collapse:separate;border-spacing:0;border:0;box-shadow:none;outline:none;background:none;table-layout:fixed;margin:0\"\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd style=\"border:0;padding:0\"\u003e\n\u003ch3 style=\"margin:1.25em 0 0.5em\"\u003e\n\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 24 24\" width=\"18\" height=\"18\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.75\" stroke-linecap=\"round\" stroke-linejoin=\"round\" style=\"display:inline-block;width:1.1em;height:1.1em;vertical-align:-0.18em;margin-right:0.45em\" aria-hidden=\"true\"\u003e\u003cpath d=\"M4 17v2a2 2 0 0 0 2 2h12a2 2 0 0 0 2 -2v-2\"\u003e\u003c\/path\u003e\u003cpath d=\"M7 11l5 5l5 -5\"\u003e\u003c\/path\u003e\u003cpath d=\"M12 4l0 12\"\u003e\u003c\/path\u003e\u003c\/svg\u003eDownloads\u003c\/h3\u003e\n\u003cul\u003e\u003cli style=\"margin:0 0 0.35em\"\u003e\u003ca href=\"https:\/\/audioresearch.com\/new_website\/wp-content\/uploads\/2026\/06\/S-200-Owners-Manual.pdf\" target=\"_blank\" rel=\"noopener nofollow\"\u003eOWNERS MANUAL\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Audio Research","offers":[{"title":"Default Title","offer_id":43181683277922,"sku":null,"price":12950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2475\/2780\/files\/s-200-stereo-power-amplifier-1.jpg?v=1786011265","url":"https:\/\/pearlaudio.com\/products\/s-200-stereo-power-amplifier","provider":"Pearl Audio","version":"1.0","type":"link"}
