As I replied to Abal, even parallel capacitance as a "power factor correction" will, together with the series inductance of the circuit (and perhaps even an inductor in the magic box) create a second order low pass filter - but maybe just maybe it works as you say it does, and maybe that is desireable.
IF that is the case ... why not just make add-on boxes with leads on them instead of making whole cables? Jack Bybee does this, Walker does this, there are a couple of aftermarket boxes that work in this gap - why not MIT and Transparent? They aren't selling cables, per se - they are selling cable-fixers. So why not fix a greater variety of cables with the magic boxes?
And if the magic box prevents reflected energy from returnining to the feedback loop of an amplifier, would it be safe to assume that they wouldn't have this effect with amplifiers such as zero-feedback SET types?
And cables that are THAT reactive are just poorly designed, IMHO. But as you say, "This explains why synergy is so critical when trying to optimize your setup, and why a particular cable set works differently when placed into different electrical environments. This is an unavoidable fact of life for any cable." - basically we understand each other in that these magicboxes cannot be optimized for all systems, but can fit only particular systems and this with only varying degrees of optimization depending upon how far from the original modeled system the system under test falls.
