Upgrade your music source.
XPS Power Supply

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 NDS, NDX and ND5 XS network players and HDX hard-disk player/server. Its large toroidal transformer features six separately regulated, low-noise outputs and benefits from Naim Audio DR voltage regulator technology.


  • Six separately regulated low-noise outputs plus six power regulators
  • 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.
