Re: OK, how about them cable risers?

If you've ever listened to them, you know they make a difference (especially if you are raising them off of carpeting). The question is "why?". It would seem that the two most obvious possibilities are:

1) Reducing or changing the interaction between the electromagnetic field from the cable; or,

Well, the electric and magnetic fields are modified by the medium which they propagate through. With the possible exception of nails and rebar, there's not much to affect the magnetic field. Carpeting and the like would act as a polarizable medium which would affect the electric field.

2) Changing the mechanical resonance characteristic of the cable itself.

Provided the mechanical resonance were in the audio band.

Does anyone have any other ideas?

There's always the psychological aspect to consider.

Does anyone have some good ideas about how to test to see which hypothesis might be correct?

Dielectric and magnetic effects would manifest themselves as changes in the cable's capacitance and inductance. And mechanical resonance would manifest itself as a peak or peaks in frequency response measurements or impedance measurements.
