Naim Audio CD5si Compact Disc Player The CD5si name may only differ from its CD5i predecessor by one character, but under the skin there's numerous fundamental improvements and advances - each one aimed at extracting more music and enjoyment from every CD. To begin with, the CD5si digital to analogue converter chip has been upgraded to a Burr Brown PCM1793 - a device very closely related to the one used in the NDX high-end streaming player. The CD5si also benefits from a more stable DAC clock, higher voltage power supply rails, a revised analogue filter design and a brand new CD transport and laser optics. It goes without saying of course that all these changes were driven by our relentless search for engineering reliability, sound quality and audio performance, and the benefit of each change was confirmed after many hours of listening. However, just as change can bring improvement, there's often nothing wrong with sticking to your guns, so the CD5si retains all of its predecessor’s best features and Naim trademarks. The unique Naim swing-out CD drawer, in-house and industry standard CD transport, laser tracking and digital error correction software, discreet analogue output electronics, and a die-cast, non magnetic enclosure construction that helps ensures the electronics within can extract the most possible music from every CD.
