The 820S<\/strong> is the large and eagerly anticipated power supply that offers an upgrade path for certain models. Making use of everything we know about power supply design with respect to circuit layout, filtration and regulation has gone into the 820S<\/strong>.<\/p>\n Featuring state-of-the-art, custom-built dual toroidal transformers, choke filtering, and our own MOON<\/strong> Reference Regulation System (M-R2S) circuit, the 820S<\/strong> is capable of doing what was once thought of as virtually impossible: improving on the already superlative power supplies built into our products, by further reducing the noise floor while maintaining an even greater voltage stability. The astonishing sheer \u201cblackness\u201d of the musical background created by the addition of this power supply must be heard to be believed.<\/p>\n Designed to elevate the performance of products that already perform stratospherically at their price points, the 820S<\/strong> was created through painstaking R&D, creative ingenuity and a passion for perfection.<\/p>\n The 820S<\/strong> is equipped with two sets of outputs; It can upgrade the performance of any one, or any combination of two of the following MOON<\/strong> series products simultaneously: 740P<\/strong>Preamplifier, 650D<\/strong> and 750D<\/strong> DAC \/ CD Transports, 780D<\/strong> DAC \/ Network Player, 610LP<\/strong> and 810LP<\/strong> Phono Preamplifiers.<\/p>\n Each output provides DC power for both analog circuitry (audio) and digital circuitry (controller, CD transport).<\/p>\n <\/p>\n Experience unparalleled performance with the MOON 820S<\/strong>, a cutting-edge power supply designed to elevate the capabilities of select MOON<\/strong> series products. Featuring custom-built dual toroidal transformers, choke filtering, and our proprietary MOON<\/strong> Reference Regulation System (M-R2S), the 820S<\/strong> sets a new standard in power supply design. With its exceptional noise reduction and voltage stability, this upgrade path for compatible models promises an astonishingly musical background.<\/p>\n","protected":false},"featured_media":38862,"template":"","meta":{"_acf_changed":false},"product_brand":[771],"product_cat":[289],"product_tag":[],"class_list":{"0":"post-38871","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-moon-by-simaudio","7":"product_cat-power-supplies-controllers-and-conditioners","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"purchasable","14":"product-type-variable"},"acf":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product\/38871","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":1,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product\/38871\/revisions"}],"predecessor-version":[{"id":49484,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product\/38871\/revisions\/49484"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/media\/38862"}],"wp:attachment":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/media?parent=38871"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product_brand?post=38871"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product_cat?post=38871"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product_tag?post=38871"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/08\/MOON-Reference-820S-Power-Supply-desc.jpg\")
