Inside and outside, Envy is a prestige product that belongs in a reference Hi-Fi rack.\u00a0Its balanced pre-amplifier outputs allow you to\u00a0operate\u00a0it just that way into a full-sized, stereo power amplifier, passing through the entire 6SN7-300B stage and out through the rear. Definitely place Envy somewhere prominent: you won&#8217;t be able to tear yourself away from gazing upon\u00a0its beautiful wood build, nor hearing this pinnacle, for long. Otherwise, seek Feliks Audio&#8217;s other OTL builds if you&#8217;re looking for a smaller footprint here, and our other amplifiers here.","og_url":"https:\/\/theaudiopeople.com.vn\/vi\/san-pham\/feliks-audio-envy\/","og_site_name":"The Audio People","article_modified_time":"2026-03-12T12:44:53+00:00","og_image":[{"width":1000,"height":1000,"url":"https:\/\/theaudiopeople.com.vn\/wp-content\/uploads\/2025\/10\/FeliksAudioEnvyOak_01_1000x.webp","type":"image\/webp"}],"twitter_card":"summary_large_image","twitter_misc":{"\u01af\u1edbc t\u00ednh th\u1eddi gian \u0111\u1ecdc":"3 ph\u00fat"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/","url":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/","name":"Feliks Audio Envy - The Audio People","isPartOf":{"@id":"https:\/\/theaudiopeople.com.vn\/#website"},"primaryImageOfPage":{"@id":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/#primaryimage"},"image":{"@id":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/#primaryimage"},"thumbnailUrl":"https:\/\/theaudiopeople.com.vn\/wp-content\/uploads\/2025\/10\/FeliksAudioEnvyOak_01_1000x.webp","datePublished":"2025-10-05T09:44:56+00:00","dateModified":"2026-03-12T12:44:53+00:00","breadcrumb":{"@id":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/#breadcrumb"},"inLanguage":"vi","potentialAction":[{"@type":"ReadAction","target":["https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/"]}]},{"@type":"ImageObject","inLanguage":"vi","@id":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/#primaryimage","url":"https:\/\/theaudiopeople.com.vn\/wp-content\/uploads\/2025\/10\/FeliksAudioEnvyOak_01_1000x.webp","contentUrl":"https:\/\/theaudiopeople.com.vn\/wp-content\/uploads\/2025\/10\/FeliksAudioEnvyOak_01_1000x.webp","width":1000,"height":1000},{"@type":"BreadcrumbList","@id":"https:\/\/theaudiopeople.com.vn\/product\/feliks-audio-envy\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/theaudiopeople.com.vn\/"},{"@type":"ListItem","position":2,"name":"Products","item":"https:\/\/theaudiopeople.com.vn\/shop\/"},{"@type":"ListItem","position":3,"name":"Feliks Audio Envy"}]},{"@type":"WebSite","@id":"https:\/\/theaudiopeople.com.vn\/#website","url":"https:\/\/theaudiopeople.com.vn\/","name":"The Audio People","description":"","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/theaudiopeople.com.vn\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"vi"}]}},"_links":{"self":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product\/11252","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/comments?post=11252"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/media\/13991"}],"wp:attachment":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/media?parent=11252"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product_brand?post=11252"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product_cat?post=11252"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product_tag?post=11252"},{"taxonomy":"pa_accessories","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_accessories?post=11252"},{"taxonomy":"pa_headphones","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_headphones?post=11252"},{"taxonomy":"pa_connection","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_connection?post=11252"},{"taxonomy":"pa_fit","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_fit?post=11252"},{"taxonomy":"pa_type","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_type?post=11252"},{"taxonomy":"pa_cases","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_cases?post=11252"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
