Twelve years after Naim revolutionised the design of Compact Disc players, the Naim CDS3 CD player + XPS2 power supply sets an impressive standard for high quality Compact Disc replay.
All the trademark features of a Naim player are brought together in the Naim CDS3 + XPS2 CD player along with a host of new and innovative engineering solutions pioneered during the development of the flagship NAC552 and NAP500 amplifiers. Together with the elegant styling, the result is a truly stunning, thoroughly satisfying musical performance.
The Naim CDS3 CD player + XPS2 power supply features the latest generation Philips CD10 transport using a high quality hall motor disc drive VAM 1202 mechanism. The crucially important suspension system for the transport consists of three precisely tuned leaf springs to optimise servo operation. Two further independent suspension arrangements isolate both the digital and analogue circuit boards from the environment, using optimally damped spring decoupling.
A separate, fully optimised master clock controls digital to analogue conversion and the clock circuit configuration and layout are engineered to minimise jitter that is further reduced by special Naim designed data re-clocking circuitry. A seven-pole analogue filter follows the DAC to remove spurious noise. The current to voltage conversion stage and all analogue filter stages use discrete transistor amplifiers to optimise performance.
The Naim CDS3 CD player + XPS2 power supply has 26 low-noise, regulated power supplies on the main circuit board, fourteen on the analogue output board and four on the servo board. Power for the whole machine is provided by the XPS power supply, which has six separately regulated, very low-noise outputs. Thus all critical circuitry is triple regulated.
Naim research proved that divorcing the main power supply in this way is wholly beneficial, whereas the more common arrangement of housing the converter circuitry in a separate box causes many problems.
To minimise coupling of external vibrations from the housing to the drive, as happens in the vast majority of players that use a drawer loading mechanism, the CDS3 has a simple and straightforward top loading system. Discs are held securely to the drive spindle by means of a low-inertia, resonance-controlling magnetically attached disc clamp, a technique that ensures rigid coupling (and mild damping) without adding to the task of the drive servo mechanism by increasing rotational inertia.
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.
