Naim XPS DR Power Supply (2003)

The importance of power supplies has been close to the heart of Naim philosophy for over twenty years. Naim research proved that divorcing the main power supply from a CD player is wholly beneficial, whereas the more common arrangement of housing the converter circuitry in a separate box causes many problems.
The Naim XPS2 power supply is a very 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.
With Naim XPS2 power supply the addition of anti-vibration, resonance-controlling feet compliment the elegant new cast and extruded anti-magnetic chassis protect the sensitive internal components from resonance and microphonic vibration.
The Naim XPS2 power supply is required and comes as standard with the CDS3 but can also be added to the CDX2 CD player, providing a substantial improvement in sound quality and a possible upgrade path from one player to another. It also makes a worthwhile addition to the HDX hard disk player, where it delivers immediately appreciable performance benefits.
Timing, dynamic range and clarity all significantly improve by adding a Naim XPS2 power supply to a CDX2. Complex passages become more understandable, bringing far more involvement and enjoyment from the music.

DR Upgrade

Our acclaimed Discrete Regulator Technology was first introduced in 2012, and features across a range of products from power supplies and amplifiers, up to our flagship Statement.
Since its introduction, and in keeping with an on-going commitment to the sustainability of Naim hi-fi, we have offered upgrades to the DR spec from previous, non-DR versions of Classic and 500 Series products.

DR Overview

Naim has long recognised the importance of power supplies to sound quality and paid meticulous attention to optimising power supply design in its products. The addition of outboard power supplies additionally offers an established upgrade path for many Naim products, enhancing sound quality by improving the supplies themselves, by removing the electromagnetic field of the transformer and interference generated by the rectifier diodes, and by eliminating transformer vibration from the product case, so it cannot affect the circuitry. Voltage regulators are widely deployed - sometimes in series for enhanced performance - to ensure that our audio and digital circuits operate with a stable, low noise supply voltage, thereby maximising their performance.
A voltage regulator is an electronic device designed to maintain a constant DC output voltage regardless of fluctuations in its supply voltage and variations in current draw from its output. An ideal voltage regulator would add zero noise and have zero output impedance - but all practical voltage regulators generate finite output noise and show some transient variation in output voltage if current demand changes suddenly. In developing the Naim Discrete Regulator we have created a discrete-component regulator that betters industry standard monolithic voltage regulators in these respects and, even more importantly, has had its design and component selection refined in the listening room to deliver maximised sound quality from Naim’s audio circuits.
