{"product_id":"audio-research-i70-integrated-amplifier","title":"Audio Research I\/70 Integrated Amplifier","description":"\u003cp\u003eThe I\/70 combines Audio Research separates in a single compact package, its visual design taking cues directly from the Reference 330M. The same output transformer used in the famed Reference 75 amplifier is paired with four KT120 output tubes to produce 70 watts per channel, governed by auto-bias, with independent tube preamplifier and tube amplifier sections and a 75-step volume control. The headphone output is driven by the KT120 output tubes themselves, and optional user-installable cards add an AKM Velvet Sound DAC with USB, optical, coax and Bluetooth, or MM\/MC phono with adjustable MC loading from 50 to 1k ohms.\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\u003e16.5 in W x 8.25 in H x 13.5 in D, 55 lbs\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\u003eNatural silver, black anodized\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\u003e4 balanced, 4 single-ended; optional 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\"\u003eOutput taps\u003c\/th\u003e\n\u003ctd\u003e8 and 4 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003ePower output\u003c\/th\u003e\n\u003ctd\u003e70 watts per channel continuous, 20Hz to 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTube biasing\u003c\/th\u003e\n\u003ctd\u003eAuto-bias\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 matched pairs KT120 output, three 6922 (one input, two driver)\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\u003eAKM Velvet Sound DAC with USB, optical, coax and Bluetooth; user-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.
