The all-new 3ES is our flagship electrostatic headphone amplifier and preamplifier. It shares the same architecture as our flagship WA33 dynamic headphone amplifier in a two-unit design where the top unit is an amplifier docking on the power supply using our internal coupling architecture (ICA) technology. The 3ES employs two 6SN7 driver tubes pushing four 300B power tubes as the output stage and one rectifier tube in the center of the amp. The new 3ES achieves the most ambitious dream in the audio world.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eHighlights\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp\u003eCompatible with 5-pin 580v (Pro-bias) for STAX, HiFiMan, MrSpeakers headphones\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDual headphone output [simultaneous operation]\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCompatible with all STAX, HiFiMan Shangri-la Jr., Dan Clark Audio VOCE electrostatic headphones\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTKD (Tokyo Ko-on Denpa) 4-channel balanced smooth potentiometer\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eXLR input x 2, RCA input x 1\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eUser selectable output: pre-amp or headphone\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaximum output 1500Vrms\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAnodized aluminum chassis, available in black or silver\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSelf-biasing with compatible tubes [\u003ca href=\"https:\/\/docs.google.com\/spreadsheets\/d\/1DdsZyTx3CJv9_cG9kVdCGZap-AldiTsvuY4Ms1K_p3k\/pubhtml\" target=\"_blank\"\u003echart\u003c\/a\u003e]\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDimensions [without tubes]: 17 3\/4\" (W), 7 1\/4\" (H), 13 1\/2\" (D) \/ 450.85mm (W), 184.15mm (H), 342.90mm (D), weight: 52 lbs. \/ 24 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVoltage: AC 100 - 120V 60HZ or AC220 - 240V, 50HZ, voltage built to destination country\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDesigned and assembled in New York, USA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eElite Edition Adds:\u003c\/h3\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp\u003eMundorf Supreme Silver\/Gold audio capacitors\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSingle Crystal copper hook-up and signal wires are used throughout.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAlps RK50 4-channel volume control in brass enclosure\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCardas Audio XLR and WBT RCA connectors\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e3ES Elite Edition 24k gold-plated plaque\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eIn the box\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp\u003eQuick start guide\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e3ES Standard or 3ES Elite Edition electrostatic headphone amplifier x 1\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e300B vacuum tube x 4\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e6SN7 vacuum tube x 2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e5U4G vacuum tube x 1\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e*AC power cord and audio cables are not included\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eColors:\u003c\/strong\u003e Black, Silver\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVersion:\u003c\/strong\u003e Standard, Elite edition\u003c\/p\u003e","brand":"Woo Audio","offers":[{"title":"black \/ standard","offer_id":38007496933566,"sku":"black standard","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"black \/ elite edition","offer_id":38007496966334,"sku":"black elite","price":13999.0,"currency_code":"USD","in_stock":true},{"title":"silver \/ standard","offer_id":38007496999102,"sku":"silver standard","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"silver \/ elite edition","offer_id":38007497031870,"sku":"silver elite","price":13999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/products\/DSC01778.jpg?v=1762457921","url":"https:\/\/audio46.mom\/products\/woo-audio-3es-electrostatic-headphone-amp-preamp","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
