Hello,
One reason for an upgraded power cord is RFI filtration. Most of us have our cords coming close or crossing other cords including speaker and other interconnects. Also,
Even though I have not tested it there might be something to the consistency of the speed. If you have a TT that governs the speed perfectly then it’s good to go. Last but not least is that most of us have an extra less expensive but good cable lying around. Those basic cables are very cheep. What if you move your power strip or conditioner and the power cable ends break off or short. It’s like owning a nice car and putting really bad lawn mower can gas it it. Not recommended.
