Naim CD5si CD Player
CD5si. Engineered for music.
The CD5si name may only differ from its CD5i predecessor by one character, but under the skin there's numerous fundamental improvements and advances - each one aimed at extracting more music and enjoyment from every CD. To begin with, the CD5si digital to analogue converter chip has been upgraded to a Burr Brown PCM1793 - a device very closely related to the one used in the NDX high-end streaming player. The CD5si also benefits from a more stable DAC clock, higher voltage power supply rails, a revised analogue filter design and a brand new CD transport and laser optics. It goes without saying of course that all these changes were driven by our relentless search for engineering reliability, sound quality and audio performance, and the benefit of each change was confirmed after many hours of listening.
However, just as change can bring improvement, there's often nothing wrong with sticking to your guns, so the CD5si retains all of its predecessor’s best features and Naim trademarks. The unique Naim swing-out CD drawer, in-house and industry standard CD transport, laser tracking and digital error correction software, discreet analogue output electronics, and a die-cast, non magnetic enclosure construction that helps ensures the electronics within can extract the most possible music from every CD.
The CD5si CD player, especially when partnered by the complementary NAIT 5i integrated amplifier, sets a thrilling new standard for the musical performance of entry-level hi-fi.
Designed by the same team that produced the world's finest CD player, the fabulous Naim CD555, the CD5i benefits both from shared technology and the shared passion to extract every last grain of music from the disc that it is playing.
This outstanding machine, which replaces the previous CD5i in our line-up, brings worthwhile performance benefits for users but retains the functionality and straightforward usability of the classic player.
The CD5si is designed to be the best in its class, incorporating genuine technological advances to provide a thoroughly enjoyable musical experience.
The CD5si's enhanced performance has been derived from a new DAC and power supply arrangement, optimisation of the output filter and star grounding pattern, along with upgraded components in key areas of the circuitry. These, combined with the unchanged elements such as the low-jitter clock, discrete digital and analogue power supplies, and the unique swing-out disc transport mechanism, deliver a spell-binding performance that is truly in a league of its own.
As with Naim's flagship CD555 player, integrity and stability of the RF signals read by the laser have been prime design considerations. A suspended transport and low mass magnetic clamping system ensures that the disc spins accurately and silently, unhindered by mechanical resonance. Paths between critical components are as short as possible to preserve delicate signals and each stage of the circuitry is powered by separate regulated supplies. Correct earthing is used throughout and there are no digital or headphone outputs.
The CD5si features a unique power supply incorporating separate digital and analogue transformer windings and additional screening to reduce the intrusion of RF interference from the mains supply.
Microphonic degradation of sound quality is greatly reduced by such measures as the use of low-energy-transfer feet supporting the stiff, low-vibration enclosure.
The CD5si offers convenient front loading using a custom-made, glass reinforced drawer mechanism, the mass of which has been carefully calculated to optimise rigidity and isolation.

Featuring a slot-loading mechanism, it supports CD-DA, CD-R, and CD-RW, and connects easily via USB-C plug-and-play. The elegant design, combining anodized aluminum and fused walnut, ensures durability and acoustic isolation, delivering a pure and immersive listening experience for those who appreciate high-quality audio.
In the contemporary audiophile landscape, where digital music and streaming dominate, the Ruark R-CD100 stands out as a refined tribute to the CD format, offering an elegant solution for enthusiasts who wish to rediscover the purity of uncompressed sound. Designed to integrate seamlessly with Ruark 100 series models such as the Ruark R410, R610, and R810, this CD player represents the perfect balance between tradition and technological innovation.
The Ruark R-CD100 is distinguished by a design that combines aesthetics and functionality. Its structure is crafted from a combination of anodized aluminum and fused walnut, giving the device an elegant appearance and structural robustness. The precisely machined top and bottom plates not only add a touch of class but also contribute to acoustic isolation of the internal mechanism, minimizing external vibrations that could affect sound quality.
The compact dimensions of the CD player, with a height of 45 mm, width of 175 mm, and depth of 167 mm, make it easy to place in any home environment, blending harmoniously with other components of the 100 series. Its lightweight design, at 1.2 kg, further simplifies handling and placement.
At the heart of the Ruark R-CD100 is a high-precision slot-loading mechanism, engineered to ensure accurate disc reading and longer lifespan compared to traditional tray-loading systems. This mechanism is compatible with a variety of disc formats, including CD-DA, CD-R, and CD-RW, offering notable flexibility for playing different types of media.
Integration with 100 series systems occurs via a USB Type-C connection, supporting USB 2.0 and 3.0 standards, ensuring stable and fast data transmission. Once connected, the player is automatically recognized by the system, appearing as an additional source on the main unit’s display. This plug-and-play approach simplifies installation and use, eliminating the need for complex configuration.
A key feature of the Ruark R-CD100 is the absence of an internal digital-to-analog converter (DAC). This design choice allows the player to take advantage of the advanced DACs present in 100 series devices, ensuring superior sound quality and tonal consistency across different sources. The result is detailed audio reproduction, with extended dynamic range and fidelity that satisfies even the most discerning listeners.
In terms of power, the player requires a 5V USB input with a maximum current of 1A, corresponding to a power consumption of 5W. This low energy requirement makes it efficient and easily powered via standard USB ports on compatible devices.
