Double Wolfson WM8742 DACs represent a significant increase in performance compared to the award-winning predecessor model of the 651C and are implemented in a double differential configuration (each channel has its own DAC for processing information). A sophisticated 2-pole Dual Differential Double Virtual Earth Balanced Bessel filter arrangement filters noise and distortion almost completely out of the DAC signal. This gives you a unique performance level. The new DACs are also equipped with a digital filter with three settings.

This allows you to choose how you want to listen to your music: The steep drop filter (steep) has a strong attenuation of aliasing images outside the passband (i.e. above 22.05 kHz) at the expense of some pre- or post-ringing in the time domain. The linear phase filter uniquely has a constant group delay that delays all audio signals equally at all frequencies, which means that the entire audio signal is present at the output with full temporal coherence. The smallest phase does not have a constant group propagation time; rather, the coefficients have been optimized without co-coupling, so that the impulse response has no pre-ringing in the time domain.

Cambridge Audio 's S3 Custom CD ServoTM System for CDs only uses a specially designed chipset and the latest double-sided surface mount technology with ultra-short signal paths without cable connections. Circuits and software have been designed with the utmost care, and S3 allows dynamic adjustment of the laser's focusing, tracking and output power in real time, which ensures the best possible reading of digital information and minimizes jitter. All this is made possible by a powerful ARM7 processor and complemented by a high-precision master clock oscillator and the very precisely developed clock buffering method matched to the impedance.

The very proven transport ensures incredible stiffness, and the CD tray itself has been designed so that its operation feels gentle and noble. An inverted black DFSTN (Double Film Super Twisted Nematic) display gives you feedback on the 651C's features, which now include CD text support. As with all Azur CD players, a high-quality toroidal transformer ensures lower noise and less waveform distortion and thus a quieter power supply.
