Dielectric Absorption is far from a theory and, as anyone that knows anything about cables is aware; they all exhibit capacitance. Much of what takes place(over time), is a stabilization of the, "charge" that the cable's dielectric assumes. Those with air, vacuum or actively biased dielectrics do not seem to take as long to stabilize, which would support that conclusion. Still; there seem to be other things taking place, within the conductors themselves. Most cables, when moved or left without voltages/signals present, will require some time to stabilize again.
