As for cable lifters, there are some who've taken measurements and reported it. Roger Skoff explains it here:

He noted that the measured capacitance changed every time a speaker cable was lifted, foot by foot, until the entire cable was off the floor. He goes onto explaining why a floor becomes part of the capacitance equation and needs to be addressed.
All the best,
