Power tubes are the directly heated 300B tubes, and the output transformers are custom-made high-end audio units made by EDIS Ogonowski. The mains transformer is also an audio-grade unit by EDIS. \u003cbr\u003e\u003cbr\u003eBiasing is fully automatic bias, and the electrical circuits are a zero-feedback design. The power tubes are heated with DC via a special circuit that's separate from the audio path. The power supply for anode voltages is based on MOSFET transistors and low-noise current sources. \u003cbr\u003e\u003cbr\u003eThe XLR balanced inputs use symmetrical high-end audio grade Lundahl transformers. Audio source selection is made using high-end relays, which are placed directly behind the input connectors, in order to limit interference and noise.\u003cbr\u003e\u003cbr\u003eThe amplifier is made using \"point to point\" technology. All wired connections are custom-made from single crystal copper (UPOCC) with a Teflon dielectric.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Power:\u003c\/strong\u003e 8 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Complement:\u003c\/strong\u003e 2 x 300B, 2 x PsVane CV-181 mk2 (6SN7)\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e 2 x RCA, 2 x XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (RCA, XLR):\u003c\/strong\u003e 100 kΩ, 10kΩ\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1x RCA pre, 1 x XLR pre, 6.3mm, XLR headphone\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 13.7\" x 13\" x 7.3\"  (35 × 33 × 18.5 cm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 33.3 lb\u003cbr\u003e\u003c\/p\u003e","brand":"Feliks Audio","offers":[{"title":"Oak \/ Standard","offer_id":42001449550008,"sku":"FLA-ENVY-OAK-OPEN","price":8199.0,"currency_code":"USD","in_stock":true},{"title":"Oak \/ Performance","offer_id":42001449582776,"sku":"FLA-ENVY-OAKP-OPEN","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"Walnut \/ Standard","offer_id":51577025560760,"sku":"FLA-ENVY-WAL-OPEN","price":8199.0,"currency_code":"USD","in_stock":true},{"title":"Walnut \/ Performance","offer_id":51577025593528,"sku":"FLA-ENVY-WAL-P-OPEN","price":8999.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/wallnut_front_197d5451-4d05-49d3-8868-86eb5932da6f.png?v=1741630436","url":"https:\/\/upscaleaudio.pro\/products\/feliks-audio-envy-headphone-amplifier-open","provider":"Upscale Audio","version":"1.0","type":"link"}
