{"product_id":"reference-7-line-stage-preamplifier","title":"Reference 7 Preamplifier","description":"\u003cp\u003eDerived from the same ground-up development platform that produced the flagship Reference 20, the Audio Research Reference 7 line-stage preamplifier brings the essential advances of that design into a focused, purist expression. Rather than adapting an existing model, it establishes a new performance benchmark built around a multi-metal layered chassis that manages resonance through controlled energy distribution and custom suspended, mass-loaded circuit boards that protect signal-path integrity.\u003c\/p\u003e\u003cp\u003eThe power supply transitions to solid-state regulation for an exceptionally low noise floor and enhanced long-term stability, while reference-grade output coupling capacitors preserve signal purity throughout. The result is a level of clarity, spatial resolution, and sheer presence that advances beyond the prior flagship—delivering extraordinary detail retrieval without sacrificing the supple, textured musical character that makes extended listening both revealing and effortless.\u003c\/p\u003e","brand":"Audio Research","offers":[{"title":"Default Title","offer_id":43181746552930,"sku":null,"price":28000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2475\/2780\/files\/reference-7-line-stage-preamplifier-2.jpg?v=1786016089","url":"https:\/\/pearlaudio.com\/products\/reference-7-line-stage-preamplifier","provider":"Pearl Audio","version":"1.0","type":"link"}
