{"product_id":"spectral-audio-sdr-4000sl-cd-player","title":"Spectral Audio SDR-4000SL CD Player","description":"The Spectral Audio SDR-4000SL is a reference compact disc player featuring a beltless modular UltraDrive transport with glass optics, 44.1 kHz playback, four custom 24-bit DACs in a double-balanced configuration, and 8x oversampling with 56-bit digital filtering. Designed to anchor ultimate two-channel audio systems, this component treats Redbook media as a true high-resolution format. It slaves the optical drive directly to the master clock to eliminate transport jitter, employing a proprietary HDCD Long Filter software algorithm for extraordinary timing precision. The architecture uses eight discrete power supplies alongside a Class A differential current-to-voltage conversion stage and a passive output equalizer wound with custom silver litz wire chokes.\n\nCritical consensus praises this component for delivering electrostatic clarity, expansive soundstage depth, and an organic warmth that rivals elite analog front ends. Reviewers highlight its ability to unearth low-level micro-dynamics and harmonic textures that standard integrated-circuit CD players fail to resolve. It remains celebrated across audio publications as a landmark engineering effort that redefines the absolute performance limits of compact disc playback.\n\nIntegrating this reference player into your system recovers the life, spatial depth, and emotional realism buried within your disc collection. It provides music lovers with an effortless, transparent presentation that makes every recording sound remarkably vivid and complete.","brand":"Spectral Audio","offers":[{"title":"Default Title","offer_id":67677971939609,"sku":"99065","price":6099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/99065-3.jpg?v=1791405736","url":"https:\/\/tmraudio.com\/products\/spectral-audio-sdr-4000sl-cd-player","provider":"The Music Room","version":"1.0","type":"link"}
