Interesting highlights
The Cyrus QX is a high performance DAC module of very advanced specification. In keeping with the Cyrus tradition of low-obsolescence and up-gradeability the module builds on the considerable strengths of the Cyrus Pre XP d.
All of the features of the Pre XP d, plus the additional advantages of the QX DAC:-
• The QXmodule features quartz reference anti jitter circuits to re align the edges of the digital signals coupled with upsampling to 192kHz. This eliminates timing errors which manifest themselves as unwanted signals in the output.
 • A 24Bit integrated filter DAC delivers state of the art technical performance in noise, distortion and linearity. This exceptional low level response allows small signals to be conveyed more faithfully.
• The analog filter is a low noise 4 pole design, giving flat response across the audio band, with rapid attenuation of the high frequency digital images.
• Specially chosen components and the widespread use of SMD devices minimises path lengths and component leadout wires. This together with extensive power supply decoupling and star earthing enables the QXmodule to perform with complete freedom from noise and instability, resulting in outstanding low-level resolution and clarity.
