Its massive transformer, some 40 percent larger than that fitted to our <strong>XPS<\/strong>power supply, features five separate windings outputting to seven regulated supply voltages, including an output specifically intended for use with the clock circuitry of our <strong>CD555<\/strong>.<\/p>\n<p>The <strong>555 PS<\/strong> was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for <strong>Naim Audio<\/strong> power supplies. The new <strong>Naim Audio DR<\/strong> now features, alongside improvements to the wire routing, mechanical decoupling and internal layout. These enhancements, developed through intensive listening tests, significantly raise performance and make music even more communicative and enjoyable.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-46007\" src=\"https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc.jpg\" alt=\"\" width=\"1290\" height=\"450\" srcset=\"https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc.jpg 1290w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc-400x140.jpg 400w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc-768x268.jpg 768w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc-430x150.jpg 430w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc-700x244.jpg 700w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2026\/01\/Naim-555-PS-DR-Power-Supply-desc-150x52.jpg 150w\" sizes=\"auto, (max-width: 1290px) 100vw, 1290px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Not everyone sees hi-fi as we do.
