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. That is also the reason why power cables have effect. Your equipment has less hard work to do when it converts AC to DC and they don't interfere as much with other cables.
Keep power & low-level cables separate (at least 3 inch), shield low-level cables & cross at 90 degrees and you're almost done. You can also check the voltage on the ground line of your power strip because it can fluctuate when you move cables.
Best tip: don't touch it when its fine ;)
