COMBO Naim DAC + Naim XP5 XS (Used 2011-2012)

Combo included Naim DAC and NAIM XP5 XS (Used 2011-2012)


The Naim DAC marks a technical milestone comparable to our first CD player, the CDS. The CDS demonstrated that CD replay and lifelike music reproduction were not mutually exclusive. Now, the Naim DAC demonstrates that the jitter and noise that bedevil traditional external digital to analog conversion can be overcome and a new route to the real enjoyment of music opened. The Naim DAC provides eight S/PDIF inputs, two USB inputs, and is capable of handling audio data sampled at up to 768kHz and with up to 24bit resolution. It not only brings all the digital inputs together into the analog domain but does so with a level of performance that can compete with the finest from any Naim CD player to provide unrivaled musical fulfillment.


Listening to the Naim DAC is a revelation. Music, whether its source is an iPod, a CD or a high-resolution data file, is presented afresh, with more definition, more insight, more warmth, and simply more of those hard-to-define clues of rhythm, melody, and emotion that distinguish the real thing from a pale imitation. The Naim DAC is an advance that brings real music in the home closer to reality than ever before.


The XP5 XS features the "slimline" XS style enclosure constructed from aluminum extrusions and high-pressure die-castings with a fine brushed anodized front panel finish. Internally the XP5 XS incorporates a massive 400VA transformer, tantalum output capacitors, low capacitance ceramic heat sinks and large smoothing capacitors. As with all Naim external power supplies, component and PCB layout is configured specifically to maximize supply stability and absolutely minimize electronic noise. The XP5 XS is hand wired and fitted with sockets selected and engineered to help minimize microphone.

Features Naim DAC

Designing an external digital toato analoguenverter capable of offering the exceptional musical performance obligatory for a Naim product brings numerous technical challenges. In particular, the S/PDIF interface protocol for digital interconnection has significant jitter and noise problems.

Original solutions to these problems had to be conceived and developed. The Naim DAC has more in common with Naim CD players than with conventional external digital to analogue converters. It overcomes the jitter issues of S/PDIF by reading the data into a "rotating" data RAM buffer independently of its timing signal and reading it out again clocked by one of ten extremely low noise, fixed frequency crystal sine-wave oscillators.

In terms of system topology, the DAC's rotating memory is analogous to a rotating CD feeding raw data to be reclocked. The rate at which the memory fills and empties is controlled by the DAC automatically selecting the oscillator that matches the average incoming clock frequency. The data entering the downstream digital filtering and DAC chips is then completely isolated from the incoming S/PDIF jitter. Along with being a source of jitter, S/PDIF is a potential source of RF noise. The Naim DAC suppresses S/PDIF noise through electrical isolation of its DSP front end from the digital to analogue converter and analogue circuits. Each element is also run from separate power supplies.

The Naim DAC's digital filtering is handled by a powerful SHARC DSP chip running unique Naim authored code to create an ultra high precision 40-bit floating point filter. The filter over-samples by 16 times on 44.1kHz data and provides stop-band attenuation of 180dB on all data. Following the digital filter are the two mono Burr-Brown digital to analogue converter chips, as used in the CD555 CD player. Finally the Naim DAC features a very high performance, low noise, and low distortion fully discrete analogue output stage.

Ground breaking technology and digital audio engineering, however, are purely academic. Listening to the Naim DAC is something else entirely. Startling in its clarity, arresting in its detail, beguiling in its warmth and inspiring in its rhythm, the Naim DAC seduces from the first note.

Features Naim XP5 XS

The significance of the power supply in high-performance audio electronics has always been central to the Naim engineering philosophy. Our enduring SuperCap, HiCap and XPS designs, for instance, stand as examples of the power supply's vital role, and Naim performance upgrades are in many cases enabled by the addition of an external power supply.

The development of the slimline ND5 XS network player provided the motivation for a new audio power supply that would serve both as a significant optional upgrade to that product, but also have applications throughout the Naim range. That power supply is the XP5 XS. The XP5 XS is a very high performance multi-rail power supply that borrows significantly from the Classic Series XPS. In addition to its application to the ND5 XS, the XP5 XS is able to power the CDS, CDX and CDX2 CD players, the HDX hard disk player, the NDX network player and the DAC digital to analogue converter. With such a wide range of compatibility, the XP5 XS can cost-effectively unlock numerous performance upgrade paths throughout the Naim range.

The difference wrought by an enhanced power supply is immediate and indisputable, and partnered with any of its compatible source products the XP5 XS will undoubtedly bring yet more performance and music to your Naim system.

Power supply - the unsung hero.

Power supply may not sound particularly high-tech, but without an adequately powerful, completely stable and extremely low-noise supply of electrical power, sensitive audio electronic circuits are simply unable to perform optimally. Electrical noise introduced by a power supply is particularly damaging as, once it gets in, it is almost impossible to remove. And any damage inflicted by power supply noise at the beginning of an audio chain is simply amplified along with the music.-
