Taking performance even higher, the 650C builds on the 550C by optimising a pair of WM8740 24bit/ 192kHzcapable DACs implemented in a dual differential configuration. Since each channel has its own DAC to process information, completely separate and symmetrical analogue filter circuitry can be implemented for excellent imaging. The 650C also features the more sophisticated Four-Pole Dual Differential Double Virtual Earth Balanced version of this filter resulting in an incredibly low noise floor, barely measurable distortion and ultimately unprecedented levels of performance.
After extensive listening tests, Cambridge Audios engineers decided that it was possible to raise the performance of the trusted Wolfson WM8740 DAC (Digital to Analogue Converter) to even greater levels and so this legendary 24bit/192kHz-capable DAC proudly features once again. But now, its been coupled to a new version of our proprietary Double Virtual Earth Balanced filter topology with Bessel Coefficients resulting in even greater musicality. These Wolfson DACs also feature a selectable digital filter with two settings enabling you to tailor output to best match your taste.
But arguably the most important development is the introduction of an entirely new in-house designed servo solution. Whereas many comparable CD players utilise an inferior CD/DVD-ROM derived drive, the 650C takes full advantage of Cambridge Audios audio-only, CD transport which is coupled to our new highly sophisticated S3 Custom CD ServoTM. This third generation audiophile servo employs an all-new chipset and the latest double-sided surface-mount technology for ultra short signal paths with freedom from wire links. The net result gives the 650C extraordinary ability to retrieve maximum digital information whilst maintaining extremely low jitter; the digital noise that affects your listening pleasure.
The 650Cs well-proven transport has been re-worked to facilitate even quieter operation and a new bracing mechanism (derived from the 740 Series) guarantees incredible rigidity. As with all Azur CD players, a high quality toroidal transformer ensures lower noise and less waveform distortion as well as incredibly quiet operation.
