{"product_id":"audio-research-ls-3-preamplifier","title":"LS-3 Preamplifier","description":"\u003cp\u003eThe Audio Research LS-3 is a solid-state line preamplifier that draws its inspiration from the award-winning LS3 of 1992, reimagined with contemporary circuit topology. A fully balanced differential JFET input stage feeds a bipolar voltage amplifier and Class-A output stages, executed in a dual-mono layout with separate power transformers and zero-gain cascaded voltage references. The linear power supplies are engineered to deliver low noise and the dynamic headroom that complex musical passages demand.\u003c\/p\u003e\n\u003cp\u003eHoused in an all-aluminum chassis that provides the rigidity needed to isolate the signal path, the LS-3 includes a new touchscreen display that carries forward the font style of Audio Research’s Reference GhostMeters®. The interface allows input naming, display intensity and color selection, and other setup functions. Sonically, the circuit renders sources with a rich tonal balance, speed, and a sense of energy that propels the music forward while preserving air, space, and focus within the recording.\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\n\u003ctbody\u003e\n\u003ctr\u003e\n\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;\"\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\n\u003cli style=\"margin: 0 0 0.35em;\"\u003e\u003ca href=\"https:\/\/audioresearch.com\/new_website\/wp-content\/uploads\/2026\/06\/LS-3-Owners-Manual.pdf\" rel=\"noopener nofollow\" target=\"_blank\"\u003eOWNERS MANUAL\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Audio Research","offers":[{"title":"Default Title","offer_id":43181694713954,"sku":null,"price":8950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2475\/2780\/files\/audio-research-ls-3-preamplifier-1.jpg?v=1786011834","url":"https:\/\/pearlaudio.com\/products\/audio-research-ls-3-preamplifier","provider":"Pearl Audio","version":"1.0","type":"link"}
