Wrapping a power cable reduces its ability to dissipate heat. As a result, if the conductor becomes appreciably hotter, its resistance will increase. This will cause the voltage at the input of the transformer to drop, even significantly if current draw is sufficient such as when an amplifier delivers a substantial amount of power. The space created by the "cordage" may have provided just enough air to keep the conductors cooler. BTW, DIY shielded power cords can be dangerous for this reason alone. Because of the similariy in the arrangement of ordinary power cords and the wiring in your house, improvement with aftermarket power cords whether DIY or store bought is very unlikely. The ordinary power cord is after all like extending what's already there by just a few percent. OTOH degradation of performance is a real possibility. The problem for tweakers is that by trying to solve problems which only exist in their minds, they can create very real new ones that never did exist and sometimes even convince themselves that they've made an improvement.
