The CD8 features twin custom transformers each feeding through highly regulated power supplies to the separate sections of the player. Our specially developed twin mono DACs provide outstanding performance. This player will produce stunning performance and, in the right systems, an almost holographic 3D image. The player’s performance may be further upgraded by partnering with a Cyrus PSX-R power supply, which will further enhance audio resolution. Furthermore, the CD8 owner can optionally return their player to the Cyrus factory for upgrade to full CD8x specification when funds permit.
The design of the CD8 was particularly challenging as it was a no-compromise brief – ‘design in the best power supply and use the best D/A converters available’. Of course, none of this engineering would earn the Cyrus stamp of approval without the attention of our listening team who worked for many months to fine-tune the completed prototype players. The DAC stage features two dual DACs configured in a true balanced topology, driving into a fully balanced analogue filter stage. The power supply design of the CD8 is the most sophisticated yet for a Cyrus CD player featuring twin power transformers, an extensive array of selected reservoir capacitors and a bank of power regulators.
The DAC technology and components used in the analogue filter stages are chosen carefully to deliver musical and technical performance to the exacting standards demanded by the Cyrus team. Whilst the balanced topology featured internally in the DAC/analogue stages of the CD8 requires duplication of many costly components, we have found it essential to extract the last ounce of performance from our CD player.
Clock stability is a key element in the signal processing chain in a player of this standard. The digital engineering of the CD8 therefore includes a remote re-clocking circuit with close-tolerance crystal VCO located at the DAC threshold to maximise jitter rejection.
Packed into the stylish, compact chassis of the CD8 are two completely separate toroidal power transformers. One transformer has two entirely separate secondary windings dedicated to feeding the electronics of the disc-reading mechanism and the current hungry motors. The second power transformer, also with two windings, is dedicated to supplying DAC & filter stages. The transformer pair are housed in the forward section of the chassis to minimise interaction with the sensitive analogue output stage. In true Cyrus style the PSX-R power supply may also be connected to further refine the power supply system and take over power supply to the motors.
Cyrus products have always delivered sonic excellence hand-in-hand with state-of-the-art technical performance. The CD8 is no exception and Cyrus are justifiably proud of the measured performance of the CD8. With ruler-flat linearity performance, vanishingly low background noise and superb jitter rejection the CD8 will technically out-perform most players in it’s class.
A natural upgrade path for the CD8 owner is the acquisition of an optional PSX-R external DC Power supply. This unique and intelligent component allows the CD8 to tap into a massive reserve of highly regulated DC energy source. Providing a completely separate power feed for the high current demands of the mechanism motors, the PSX-R effectively removes the dynamically changing load of the motors from the internal power transformers.
