Cyrus 8XP d QX

Technical Information

All of the features of the 8XP d, plus the additional advantages of the QX DAC:-

• The QX module features quartz reference anti jitter circuits to re align the edges of the digital signals coupled with up-sampling 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 analogue 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 lead-out wires. This together with extensive power supply decoupling and star earthing enables the Qx module to perform with complete freedom from noise and instability, resulting in outstanding low-level resolution and clarity.
