Can't reach the Purifi website at the moment, but the Bruno Putzeys article on hysteresis distortion (without the animation) is attached.
Other than that, ferrite beads in dac clocking circuits have been found by multiple people to have adverse effects on perceived sound. What may be interesting is that its not clear if the effect shows up well in phase noise plots. That said, phase noise plots do not show peak jitter, and can at best only be used to estimate RMS jitter.

A series inductance of 3uH (pretty much for a ferrite bead) - that drops close to zero in case of saturation - will add non neglible distortion imho.
