{"product_id":"audio-research-ls-2-preamplifier","title":"Audio Research LS-2 Preamplifier","description":"\u003cp\u003eInspired by the original LS2 line stage of 1992, the modern LS-2 is a pure tube, zero-feedback, pure Class-A design with two 6H30 dual-triode tubes at its heart and no solid-state devices in the signal path. A single gain stage with constant-current cathode bias and a cathode follower delivers the harmonic richness and dimensionality of dual-triode vacuum tubes. An all-new touch-screen display provides input naming, intensity and color adjustment, and user-installable DAC and MM\/MC phono cards are optional.\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, 33 lbs net\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eDisplay\u003c\/th\u003e\n\u003ctd\u003eFull touch-screen with input labeling and color options\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\u003e10Hz to 40kHz (-0.3dB at rated output, balanced)\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\u003e12dB balanced and single-ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eInputs\u003c\/th\u003e\n\u003ctd\u003eBalanced XLR and RCA; optional user-installable DAC and MM\/MC phono cards\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, zero feedback, single gain stage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTube complement\u003c\/th\u003e\n\u003ctd\u003eTwo 6H30 dual triodes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOptions \u0026amp; Upgrades\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003eDAC card\u003cbr\u003e\u003csmall\u003eUser-installable\u003c\/small\u003e\n\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$1,000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003eMM\/MC phono card\u003cbr\u003e\u003csmall\u003eUser-installable\u003c\/small\u003e\n\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$1,000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003eBoth DAC and phono cards, factory preinstalled\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$1,500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003csmall\u003ePrices shown are for the base configuration.
