Featuring an all-tube signal path from ECC83 inputs to KT170 outputs, plus tube-regulated power supplies it delivers exceptional dynamics, tonal richness, precision, and realism. Despite its immense power the 330M maintains the delicacy and purity often associated with lower-powered amplifiers. It offers commanding speaker control, deep infrasonic bass, expansive soundstage detail and lifelike musical immersion. Designed as the ultimate expression of Audio Research’s heritage, the 330M brings recordings to life with remarkable clarity, emotion, and energy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e• The 330M was designed to provide ultimate performance without worry.\u003cbr\u003e• Auto bias assures rock-steady consistency, minute-by-minute, day in and day out.\u003cbr\u003e• Output tube life is 3,000 hours, providing many years of listening pleasure.\u003cbr\u003e• A fully-balanced design, the addition of single-ended inputs allows its compatibility with virtually any source.\u003cbr\u003e• 12 volt triggers allow the 330M to be turned on remotely, just by powering up your Reference preamp or a master control.\u003cbr\u003e• RS232 control.\u003c\/p\u003e\n\u003cp\u003e• Auto-off control will turn 330M off if no signal is sensed in two hours (defeatable).•\u003cbr\u003eFan speed control.\u003cbr\u003e• Tube hour meter.\u003cbr\u003e• 4-8 ohm speaker outputs.\u003cbr\u003e• Tube monitor.\u003cbr\u003e• Meter light control allows dimming or off.\u003cbr\u003e• Meter action switch allows meter needle to be turned off.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output:\u003c\/strong\u003e 330 watts\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Biasing:\u003c\/strong\u003e Auto-Bias\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Taps:\u003c\/strong\u003e 4Ω, 8Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Compliment:\u003c\/strong\u003e (6) KT170 Power Output ; (1) ECC83 \u0026amp; (1) 6H30 input ;\u003cbr\u003e(1) 6550 \u0026amp; (1) 6H30 Power Supply\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs: \u003c\/strong\u003eXLR \u0026amp; Single-Ended\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eControls:\u003c\/strong\u003e 12V Triggers ; RS-232 Remote Control\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Saving:\u003c\/strong\u003e Standby Mode\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 101 Ibs\u003c\/p\u003e","brand":"Audio Research","offers":[{"title":"Silver","offer_id":51581373022496,"sku":null,"price":45000.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":51581373055264,"sku":null,"price":45000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/3728\/1568\/files\/editARReference330MPowerAmpsilverfrontwhitebackground.jpg?v=1778096823","url":"https:\/\/salon1audio.com\/products\/audio-research-reference-330m-monoblock-power-amplifier","provider":"Salon 1 Audio","version":"1.0","type":"link"}
