{"product_id":"audio-research-s-100-stereo-power-amplifier","title":"Audio Research S-100 Stereo Power Amplifier","description":"\u003cp\u003eThe S-100 answers founder Bill Johnson's demand that solid-state designs never fail to engage the listener. Like the S-200, it is a pure Class A\/B design on a dual-mono platform, conservatively rated at 100 watts per channel and doubling into 4 ohms via dual toroidal transformers and a fully balanced stereo circuit, with bipolar transistors chosen over MOSFETs. The machined aluminum chassis in black or silver anodized finish features custom machined heat sinks with no visible fasteners from the front or top, and every unit is produced in the Minnesota facility alongside the Reference tube amplifiers.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e19 in W x 7 in H x 17.5 in D, 41 lbs net\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eFrequency response\u003c\/th\u003e\n\u003ctd\u003e20Hz to 20kHz (+\/-0.1dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eGain\u003c\/th\u003e\n\u003ctd\u003e26dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eInput impedance\u003c\/th\u003e\n\u003ctd\u003e100K ohms balanced or single-ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003ePower output\u003c\/th\u003e\n\u003ctd\u003e100 watts per channel into 8 ohms, 200 watts into 4 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTHD\u003c\/th\u003e\n\u003ctd\u003eLess than 0.1% from 0.25W to rated output into 8 ohms at 1kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTopology\u003c\/th\u003e\n\u003ctd\u003ePure Class A\/B, dual mono, fully balanced, bipolar output devices\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eCall or visit the showroom about availability.\u003c\/strong\u003e Contact our team for pricing, a demonstration, or system design — \u003ca href=\"\/pages\/contact\"\u003eget in touch\u003c\/a\u003e.\u003c\/p\u003e","brand":"Audio Research","offers":[{"title":"Default Title","offer_id":50417943380161,"sku":null,"price":9450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0869\/8340\/9857\/files\/Product-grid-S-100_361daa93-35fd-472d-a33e-2b19bc3184f8.jpg?v=1785024463","url":"https:\/\/soundsanctuaryaustin.com\/products\/audio-research-s-100-stereo-power-amplifier","provider":"Sound Sanctuary Austin","version":"1.0","type":"link"}
