Coherent Systems Oracle Audio | CD2500 MK IV Player

Description

Oracle analogue and digital products have always been designed and built as “musical instruments” that can stand the test of time. It is our belief that achieving simplicity in design is a combination of knowledge and common sense.

A properly designed device creates its own form; one that reflects the beauty of its function. True artistry combines these elements by means of the whole being greater than the sum of its parts.

Many of the problems that affect the accurate reproduction of recorded music derive from unwanted internal or external vibration. To address this issue the CD2000 MkIII and CD2500 MkIV use a massive aluminum floating chassis and a Delrin decoupling system of the cd drive.

Furthermore, our unique suspension and disc clamping systems originally used in our analog turntables, have been adapted for use in our “State of the Art” CD Players.

The CD2500 MkIV harbors a new DAC board that uses the Burr Brown PCM1792 which allows input and output of digital data of up to 24bits/192khz. The CD player uses four independent and fully discrete analog modules, one for each of the analog signals from the PCM1792.

These analog modules which have been further improved from previous versions are at the center of the music reproduction quality.

The CD2500 MkIV can be used as your reference DAC for other digital sources since it features a SPDIF digital signal input.

Both the CD2000 MkIII and CD2500 Mk IV have had their power supply stage totally redesigned. There is better realism, more dynamics and we are closer to a true analog-like sound than ever!

Craftsmanship

In order to achieve an impeccable natural finish on most of the machined parts, diamond cutting tools are used extensively. Each aluminium component is hand brushed and coated with a high gloss polyester lacquer to seal and preserve the beautiful natural appearance.

At Oracle Audio Technologies, people make the difference in manufacturing, they are craftsmen devoted to serving our customers. Their work creates pride of ownership; their passion for detail shows at every step of the manufacturing process. Their manufacturing techniques and skills result in a work of art.

The floating chassis

The floating chassis plays an important role within the CD 2500 and CD 2000; it must rigidly support both the mechanism and the adjacent electronics.

Its maximum rigidity, its minimal surface area and energy control are key its design parameters. The floating chassis system as a whole, due to its high mass, contributes in effectively controlling vibrations with the aid of additional mechanical filters.

The chassis nylon sleeve within the Cd enclosure eliminates the high frequencies, the Delrin drive decoupling pillars remove medium and high frequency interferences from the vicinity of the drive mechanism.

Finally, a Urethane compound acts as a mechanical energy trap reducing any remaining vibration to an insignificant level.
