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.
