{"product_id":"audio-research-reference-7-line-stage-preamplifier","title":"Audio Research Reference 7 Line-Stage Preamplifier","description":"\u003cp\u003eThe Reference 7 brings the full measure of Audio Research's latest development work to a broader expression of the reference preamplifier. Rather than adapting an existing design, it is derived directly from the ground-up platform that produced the Reference 20, carrying forward the same multi-metal layered chassis and custom suspended, mass-loaded circuit boards. Its power supply transitions to solid-state regulation for exceptionally low noise, while reference-grade output coupling capacitors derived from the flagship preserve signal purity throughout.\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 shared with the Reference 20\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\"\u003eFinishes\u003c\/th\u003e\n\u003ctd\u003eSilver, black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eOutput coupling capacitors\u003c\/th\u003e\n\u003ctd\u003eReference-grade, derived from the flagship design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003ePower supply regulation\u003c\/th\u003e\n\u003ctd\u003eSolid-state, low noise\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":50417942954177,"sku":null,"price":28000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0869\/8340\/9857\/files\/ref7-2_d4896ff9-9f45-4079-abdf-213cb5e2e623.jpg?v=1785024450","url":"https:\/\/soundsanctuaryaustin.com\/products\/audio-research-reference-7-line-stage-preamplifier","provider":"Sound Sanctuary Austin","version":"1.0","type":"link"}
