The CD5 XS uses every possible development from earlier and more costly Naim CD players to help establish it as the reference entry-level CD player. The drawer and transport suspension is borrowed from the CDX2; a low inertia, resonance-controlling device that ensures rigid coupling and mild damping without adding to the task of the drive servo mechanism by increasing rotational inertia.
The zinc and extruded aluminium casework is a development of that used in the existing 500 series and results in an inert case with great resistance to pollution from external vibration.
The CD5 XS continues the trend of the latest Naim reference products by including RCA phono sockets alongside the traditionally used DIN sockets. RCA phonos allow easy connection to non-Naim amplifiers with a variety of interconnect cables allowing fine-tuning of the sound which is potentially beneficial when used in a budget non-Naim system.
