There is no strange voodoo happening with cables moving. 1) changing antenna effect (rfi) 2) induction by magnetism off other cables (emi) 3) picked up leakage current from other cables. 4) dielectric absorption can change for a little while when you move cables 5) static interference. And all these effects are influential on your equipment's power supplies.
Very nice and IMO a very accurate, description of "what can and is" happening. ANTENNA effect. Turn off all the breakers, lest what you need. Works well, just NO domestic bliss when I pull this one. 90 on any interconnect that have to cross, and space. Certainly follows the Seymour Cray, idea that bundling cables, SLOWS and caused anomalies that could only be explained and STOPPED, by a random convergence of cabling.
In other words, "looks like a spaghetti factory" nothing neat inside one of his SUPER COMPUTERS. The only thing that slowed down the processing power of a CRAY was the speed of light. Pretty quick indeed.
Is this relative to quality sound reproduction? You be the judge, digital and analog signals just under the speed of light 185,999.999 MPS
So off the floor, spacing, cable routing, cabling covering, the neighbors HAM radio, poor shielding or INCORRECT shielding, the dog burying there dog treats in your cable nest.LOL All have effects, just some more apparent than other. It takes 45 min if I disconnect and reconnect a speaker terminal, 3-7 days if I replace a cable run, with a conditioned cable. Yup Yup..
