CDXt

The CD Xt is the transport or disc spinning half of the ultimate CD player system. At the highest levels of CD player development we have learnt that it is beneficial to separate certain sections of the CD mechanics, together with its relatively noisy associated circuitry, from some low level digital sections. The most successful way we have found to do this is to manufacture the player in two separate and isolated die-cast chassis. The benefits bring higher resolution, quieter background and improved imagery.

The matching DAC is called DAC X and can be ordered as a decoder only or as DAC XP that includes our finest preamplifier built into the same cast chassis. This integration brings several benefits because, unlike the transport, the preamplifier benefits from fewer wires and much smaller circuit topology.

With the introduction of the acclaimed DAC X and DAC XP D/A converters, Cyrus moved into a new league for replay of digital sources by offering 192kHz up-sampling, true 192kHz DACs and full differential modes of operation. Now, the long awaited CD Xt is introduced to complement the DAC XP and other established ‘X’ series components as a high-end ‘digital optimised’ CD source.

Partnered with a DAC XP and a pair of PSX-R power supplies, this four box combination re-establishes Cyrus with a high-end system to succeed the reputation of the revered Discmaster/Dacmaster/PSX-R/PSX-R system. Featuring improvements to the disc-reading servo circuit, a power supply optimised for ‘digital only’ processing and the facility to connect a PSX-R power supply, the CD Xt more than justifies its ‘X’ series status.

Clock stability is a key element in the signal processing chain in a player of this standard. The digital engineering of the CD Xt therefore includes a remote re-clocking circuit with close tolerance crystal VCO located at the threshold of the signal drive circuit to maximise jitter rejection.
Packed into the stylish, compact chassis of the CD Xt is a high quality toroidal power transformer. The transformer has two entirely separate secondary windings with one dedicated to feeding the digital electronics and the other supplying a completely separate feed to the current hungry motors. 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 CD Xt is no exception and Cyrus are justifiably proud of the measured performance of the ‘X’ series transport and DAC combination. A CD Xt partnered with a DAC X or DAC XP will deliver ruler-flat linearity performance, vanishingly low background noise and superb jitter rejection, out-performing most two box players in their class.

A natural upgrade path for the CD Xt owner is the acquisition of an optional PSX-R external DC Power supply. This unique and intelligent component allows the CD Xt 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 transformer.

The unique MC-BUS connectivity of the CD Xt 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 CD Xt is facilitated via the MC-Bus during its manufacturing process, eliminating potential human error.

The quality lightweight die-cast enclosure of the CD Xt has 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 electro-magnetic disturbances. This also eliminates coupling of the power transformer stray magnetic fields to the sensitive audio circuitry.
