Naim CDX2 CD Player

Here we have a CDX2 CD that was launched in 2002 in the “Classic” style casework, replacing as it did the “Olive” CDX. It is a single-box CD player, with another novel design twist from Naim. This features a CD transport that sits in a manually swing-out CD tray, and a special CD puck magnetically holds the disc in place. This example was actually built for a member of the Naim staff – hence no serial number and is in very good condition, with a new logo having been fitted, however please note there is some slight delamination to the screen. It is supplied in NAIM packaging, with remote control, mains cable, SNAIC, Burndy Plug, CD Puck, and our standard three month warranty.
And by the way, this is the later version (from 2010 onwards) which features a digital output so you could turn this into a two or even three box configuration by adding a Naim DAC and/or Power Supply! Just a thought….
Naim Say….
Designed well, a product should have many years of useful life. The original Naim Audio CDX debuted in 1999, and the revised CDX2 shares plenty of design DNA with its predecessor. Its radial arc disc tray is classic Naim Audio. It is different from the motorised assemblies used by other players, but undoubtedly better, with superior isolation and resistance to resonance. In its latest incarnation, the CDX2 has incorporated some useful new enhancements, including a switchable digital output and extra low-noise clock regulation. After all, being able to do something well shouldn’t stop you from trying to do it better.
Integrity and stability of the signals read by the laser were prime design considerations for the CDX2’s development. A suspended transport and low mass magnetic clamping system ensure that the disc spins accurately and silently, unhindered by mechanical resonance.
The mass of the custom-made glass reinforced front-loading drawer mechanism has been carefully calculated to optimise rigidity and isolation. Additionally, the internal shielding has been improved bringing about further upgraded performance and lower noise. Paths between critical components are as short as possible to preserve delicate signals and each stage of the circuitry is powered by a separate regulated supply.
The CDX2 has a fully double-regulated power supply with 20 low-noise, regulated power supplies on the main circuit board, plus a separate supply on the servo control board and another on the display board. The CDX2 is easily upgradable via the XPS ultra-low noise power supply to provide a substantial improvement in sound quality.
All main control functions are handled by a microprocessor running Naim Audio-written software. Every aspect of the servo controller/decoder functionality is under software control: Naim Audio-written codes allow maximised performance in all areas. For example, the transport parameters are optimised for each disc as it is loaded.
