That's not the reasoning behind the use of better power cables. Back to Anaiysis....Yes, lots of labs, analysis, and reports.
And what I learned is to get a set of baseline data, then change one variable, recollect data, then compare. If you did that with expensive power cables there's no way you would find a meaningful change in the output. But then that could be blamed on all the wiring between the expensive cable and the generator at power plant, on squirrels dancing on the wires, or maybe the witch doctor next door.
