{"product_id":"audio-research-reference-20-line-stage-preamplifier","title":"Audio Research Reference 20 Line-Stage Preamplifier","description":"\u003cp\u003eThe Reference 20 is Audio Research's flagship line-stage preamplifier, a complete rethinking of the category developed without constraint in pursuit of absolute sonic transparency. The traditional stamped chassis is replaced with a multi-metal, layered construction that disperses resonant energy, and critical circuits are mounted on custom suspended, mass-loaded boards that isolate the signal path from mechanical influence. A comprehensively redesigned power supply with advanced regulation and next-generation film capacitors lowers noise on the regulated rails by an order of magnitude, and the single-chassis REF20 surpasses its two-chassis predecessor in every respect.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eChassis\u003c\/th\u003e\n\u003ctd\u003eMulti-metal, layered construction for resonance control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eCircuit boards\u003c\/th\u003e\n\u003ctd\u003eCustom suspended, mass-loaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eConfiguration\u003c\/th\u003e\n\u003ctd\u003eSingle-chassis line-stage preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eMade in\u003c\/th\u003e\n\u003ctd\u003eMinnesota, USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003ePower supply\u003c\/th\u003e\n\u003ctd\u003eAdvanced regulation with next-generation film capacitors\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":50417942921409,"sku":null,"price":48000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0869\/8340\/9857\/files\/Ref20-top-side2.jpg?v=1785024449","url":"https:\/\/soundsanctuaryaustin.com\/products\/audio-research-reference-20-line-stage-preamplifier","provider":"Sound Sanctuary Austin","version":"1.0","type":"link"}
