The SA-11S1 is the ultimate music disc player. It helps fulfill the dream of every audiophile: A system that simply passes music from the artist’s mind to the listener’s ear. The heavy copper-plated chassis damps unwanted resonances while it shields internal circuits from destructive radio frequency and electromagnetic radiation. The resonance-free disc mechanism provides an ultra-stable platform for both disc and laser optical system. In addition to Marantz’s proprietary HDAM-SA signal transfer modules, audio circuits boast custom-selected internal components chosen for their combined contribution to overall signal quality. Output filters, long the downfall of other supposedly “top shelf” players, are custom-configured and individually selectable for both SA-CD and conventional CD playback. The result? Sound from your treasured CDs approaches that of today’s most advanced SA-CDs!
