Naim Audio XPS DR power supply

Naim Audio XPS DR power supply.


What we Say:

The Naim Audio XPS  DR is a classic Naim upgrade component. It replaces the previous non-DR version of the XPS. It provides clean power to the critical different circuits within a naim digital source component.

A digital source component features a range of complex digital and analogue circuits. Each one needs a clean stable power supply to work at its best. It is also desirable if the supplies for analogue circuits are isolated from those powering digital circuits. The XPs achieves this goal by using 6 discreet regulator circuits. These are fed from the transformer from 4 different windings each of which has a large reservoir capacitor.

The XPS DR can power a range of new and legacy products. It can be used on the CDS2, CDS3, NDX, HDX and NDX2. The CDS2 and CDS3 were originally supplied with the Non DR XPS. The other components will wort without an external supply but get a large performance lift by adding an external supply.

Adding a Naim Audio XPS DR will bring huge sonic benefits to your system. To hear them please get in touch with us.

Upgrade your music source.
The XPS is a simple and effective upgrade to enhance the music-making ability of your Naim Audio source component. As one of our most flexible performers it can be used to upgrade our CDX2 CD player and DAC digital to analogue converter, and it is also suitable for use with our NDSNDX and ND5 XS network players and HDX hard-disk player/server. Its large toroidal transformer features four separate windings, coupled to six low-noise regulators and benefits from Naim Audio DR voltage regulator technology.
  • Four isolated transformer windings with six low-noise DR power regulators – configured as two isolated regulators for digital at +15V, isolated +/-10V for DACs and isolated +/-23V for analogue stages
  • All-new Discrete Regulator (DR) configuration, delivering Naim Audio’s best-ever standards of stable, low-noise power
  • Brushed, black-anodised aluminium chassis plus anti-vibration feet
Technology & Craft

The Naim Audio XPS is a highly sophisticated power supply with six separately regulated, very low noise outputs, featuring a toroidal transformer and six power regulators. These supplies are branched and re-regulated, some twice in the CD player.

The addition of anti-vibration, resonance-controlling feet complement the elegant cast and extruded anti-magnetic chassis protect the sensitive internal components from resonance and microphonic vibration.

The XPS was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for Naim Audio power supplies. The new Naim Audio DR now features, alongside improvements to the mechanical decoupling and internal layout. These enhancements, developed through intensive listening tests, significantly raise performance and make music even more communicative and enjoyable.

A technical white paper on the Naim Audio Discrete Regulator technology is available here.

Please note: only new classic series XPS units are compatible with the NDX network player, not ‘Olive’ versions. The old ‘Olive’ XPS is still compatible with CDX and CDS model CD players, the HDX hard disk player and the DAC digital to analogue converter however. Please consult your Naim Audio retailer if you are unsure of compatibility.
