analyzing the technology of power "conditioners"

Besides the balanced power/massive toroidal approach (Equi=tech, Torus, Bryston, Furman balanced, etc.), and the power regeneration approach (PS Audio, PurePower+), there are a number of what appear to be other unique technologies out there. Or perhaps they’re not, and we just don’t know what’s going on inside those little black boxes inside the larger black boxes.

Has anyone ever come across an electrical/electronic engineer, who has actually dismantled and identified the innards and workings of the offerings of Shunyata, Audience Adept, Audioquest, Synergistic Research, Isotek, et al.? You know, the way iFixit always does a teardown of the latest iPhone.
