Naim CD5si CD player

Naim Audio CD5si CD player.


What we Say:

The Naim CD5si is now the only CD player in the Naim range. It still offers excellent performance. The player is a front loader with manual pull out tray. This removes the usual clunk CD drawer which are often prone to breaking down. It is smooth and easy to use and really makes the player stand out from the crowd. This drawer contains the transport and provides it with mechanical isolation. As usual for s Naim player the transport is a Philips unit. The disc clamps in place with a small magnetic puck.

Inside the CD5si there is a substantial linear power supply including a large toroidal transformer. This feeds the Digital and analogue sections individually with clean power. The DAC is fed with a low Jitter clock to minimise distortion and the output filter is carefully designed to minimise phase distortion. This results in the Naim players having excellent transient performance. They are known for being dynamic and exciting to listen to just like live music.

The CD5si is simple to use with just 4 buttons on the front. The remote handset controls all other functions. Connection to your amplifier is by DIN or RCA on the rear panel. For best performance in a Naim system we always recommend using the DIN connection.

Technology & Craft

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. All these changes were driven by our relentless search for engineering reliability and sound quality, 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 Audio trademarks. The unique Naim Audio swing-out CD drawer, laser tracking and digital error correction software, discrete analogue output electronics, and a die-cast, non-magnetic enclosure construction that helps ensure the electronics within can extract the most music possible from every CD.
