Cyrus CD 6 SE

Technical Information

It has always been our guiding principle that technologies developed for the X series should trickle down to the other ranges. However our special optical servo system significantly improves the data performance. Normally this type of engineering would only be found in our most expensive models but we have been able to use this circuitry throughout the CD range.

Whilst the CD 6 SE is a simpler design than the CD8 SE, it shares many aspects of the CD8 SE circuit topology. This is particularly evident in the quality of components used in the power supply, DAC and analogue filter stages. This level of component quality is unusual in a CD player in this class and is an essential part of the winning formula necessary to deliver musical and technical performance to the exacting standards demanded by the Cyrus team.

• Clock stability is a key element in the signal processing chain in a player of this standard. The digital engineering of the CD6 SE therefore includes a re-clocking circuit located at the DAC threshold to maximise jitter rejection.

• The power supply circuitry of the CD6 SE is driven from a high-grade toroidal transformer with two separate secondary windings. With this configuration it is possible to provide completely isolated power supplies for the differing power requirements of the digital and analogue sections of the player. 11 stages of power regulation provide further stage isolation and the best possible environment for the sensitive analogue stages to work in.

• Cyrus products have always delivered sonic excellence hand-in-hand with state-of-the-art technical performance. The CD  SE is no exception and Cyrus are justifiably proud of the measured performance of the CD6 SE. With ruler-flat linearity performance, exceptionally low background noise and superb jitter rejection the CD6 SE is technically superior in its class.

• In true Cyrus tradition, the CD6 SE has a clearly defined upgrade path. In fact all CD 6 model variants can benefit from the Cyrus upgrade program by returning to Cyrus for a factory upgrade to any of the SE models including, CD 8 SE or Xt SE models. The 8 and X series models include a PSX-R connection and a co-axial digital output are added. The front fascia is also changed with a CD 8 SE insignia. The PSX-R connection of the CD 8 SE and Xt SE makes a further optional performance upgrade possible.

• The unique MC-Bus connectivity of the CD 6 SE is in keeping with the total system approach of the Cyrus range of products. This facility enhances ergonomic operation of the unit in a system context. Total automation of the test, alignment and calibration of the CD6 SE is managed via the MC-Bus coms ports during its manufacturing process, eliminating potential human error.

• The quality magnesium die-cast enclosure of the CD6 SE delivers a myriad of advantages both electrically and mechanically. The non-resonant nature of the alloy minimises microphonic effects, while its non-ferrous composition provides an effective shield from external RF disturbances. This also eliminates coupling of the power transformer stray magnetic fields to the sensitive audio circuitry. Lower cost steel enclosures do not offer these benefits.
