Default Re: Audiophoolery. 'Cable Break In' - I never knew that!

Unrectifiers are unrequired. AC power flow has direction. It is given by the phase relationship of the voltage and current waveforms.

The voltage on the mains swings positive and negative, the current goes one way then the other, but the power station is driving your electric fire, not the other way round. At RF we have directional couplers to resolve forwards and backwards power flows on a line. In this way we can measure the reflectivity of a load or its VSWR without slotted lines and probes.
