Sixteen KT150 power tubes per channel deliver 750 watts continuous into loads of 4 to 16 ohms through a massive custom-built power and output transformer, with approximately 1300 joules of power supply energy storage in reserve. It is built for the largest listening rooms and the largest loudspeaker designs.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eFrequency response\u003c\/th\u003e\n\u003ctd\u003e1Hz to 200kHz (-3dB at 1 watt)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eInput impedance\u003c\/th\u003e\n\u003ctd\u003e200K ohms balanced\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\u003e4, 8 and 16 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\u003e750 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\"\u003ePower supply energy storage\u003c\/th\u003e\n\u003ctd\u003eApproximately 1300 joules\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\u003eEight matched pairs KT150 output; KT150 driver pair; 6550WE and 6H30 regulation; 6H30 follower\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e170 lbs net per monoblock\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":50417943150785,"sku":null,"price":42500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0869\/8340\/9857\/files\/REF750-1_b87939a8-e28f-415f-9e3d-cc401e6014be.jpg?v=1785024456","url":"https:\/\/soundsanctuaryaustin.com\/products\/audio-research-reference-750sel-monoblock-power-amplifier","provider":"Sound Sanctuary Austin","version":"1.0","type":"link"}
