The World's First Performance Upgradeable, Audiophile Hard Disk Player - the New HDX is launched


The HDX reads audio data from CDs, stores it on a hard disk, catalogues the artist, album and track titles and, at the touch of a screen, replays it with utterly uncompromised sound quality. The HDX's ease of use defines elegant simplicity and it even offers the option of operating as a high-end CD player by directly playing a disc loaded in its drawer.

The HDX is of course not the first hard disk music player, but it is the first to carry a Naim logo, and with it, all the principles of musical audio quality that the logo demands. It incorporates every last thing we know about maximizing the sound quality of digital audio and is the first hard disk player to reach the heady performance levels of the world' s best CD players - our own.

At the heart of the HDX is a fully integrated CD ripping and data storage system, engineered by Naim - both hardware and software - from the ground up to optimize audio quality. When a CD is inserted in the HDX drawer it is mounted on a specially selected audio grade transport mechanism and each of its data sectors read multiple times at varying rotational speeds to ensure that the subsequently stored data is "bit perfect". Unique Naim firmware effectively handles copy protected CDs that in most other hard disk music players are likely to be ripped with compromised audio quality. The same firmware also overcomes the track start and end errors that occur in most other hard disk players and ensures that artists' intended track lead in and out times are preserved - again, in contrast to most other players. The bit-perfect data is stored on two 400GB disk drives - one primary and one back up. HDX playback begins with a unique Naim designed, multiple power supply PCI interface that feeds the audio data to the digital to analogue conversion stage. The HDX digital audio architecture is not limited to 16 bit and 44.1kHz but can handle bit depths up to 24 bit and sampling frequencies up to 192kHz.



The HDX's playback electronics borrow heavily from the established Naim practices that produce the World's finest sounding CD players:

  • Independent and separately grounded multi-regulated power supplies for analogue and digital stages.
  • A Burr-Brown PCM1791A digital to analogue converter selected after exhaustive listening.
  • 24 bit/192kHz internal architecture with support for hi-resolution audio formats.
  • Ultra low jitter re-clocking circuits.
  • A seven pole analogue output filtering using Burr Brown OPA604 op amps.
  • Custom designed monolithic air core transformer isolated analogue output stages.
  • An optional external XPS or CD555PS power supply for even greater musical performance.

In use the HDX is intuitive, satisfying and simple, and, thanks to an internet connection, automatically catalogues every ripped disc. So imagine your entire CD collection available for immediate replay at the touch of a screen with Naim CD player matching sound quality. You don? t have to imagine; HDX has arrived.

New CD555 and n-Vi launched at Heathrow Hi-Fi Show

The London Hi-fi and Home Entertainment Show witnessed the first showing of the new, high-end CD555 CD player and the all-in-one DVD player and AV processor combination, the n-Vi .

The CD555, along with the 555PS power supply, represents Naim's finest reference quality CD player to date.

The top-loading player (using a motorised door) features an incredibly sophisticated new power supply, the 555PS, which is connected to the head unit with two Burndy cables - one for digital data and one for analogue signals. The supply is backwards-compatible with the existing CDS3 and CDX2 players. The DACs in the head unit are built into a 'quiet room' to isolate them from the varying electric and magnetic fields that inevitably occur in a CD player, and allowing them to work free from any disturbances.

The CD555 uses a solid, suspended, machined transport tray and a die-cast Philips Pro CD mechanism along with seven-pole output filters and a low jitter clock circuit with its own multi-stage, regulated power supply.

All this attention to detail - and more - results in what we believe to be the ultimate musical performance attainable from a CD player.



The second new product unveiled at the Hi-fi and Home Entertainment Show was the n-Vi, a high performance, all-in-one solution for music fans who wish to incorporate home cinema into their systems - as well as introducing Naim audio and video performance to a wider audience.

n-Vi is an upgradeable, high-end, integrated DVD player, DVD-A player, CD player, AV processor, audio preamplifier, and five channel power amplifier. From launch it will be available with an optional FM/DAB radio module. A video scaler module including an external video input will be available in spring 2006. Its complement of surround sound modes includes Dolby Digital, DTS and Dolby Pro Logic II, and n-Vi also features progressive scan and HCDP-enabled DVI video output for the best image performance.

Furthermore, n-Vi features a bi-directional RS232 port for connection for custom install into ‘intelligent homes’ and provides a connection for the new Naim NA-Bus for bi-directional control and interoperability with future Naim products.
