Humans vary tremendously in their ability to resolve musical details. It is not a bell shaped curve. No device can provide an absolutely accurate measure of what will work for all listeners. There is no single audio component solution, including cables, that will work for everyone. Learn something about the human auditory system and stop focusing on hardware that is distal to the PNS and CNS.
Cables ... no longer opinion
PS Audio has already did the research. The answers are available forevermore.
The testing is sound, and not flawed. Their test results find exactly the same results my cable manufacturer found and preached. Josh from Downsize Audio Cables also found two strips of foils, stacked on top of each other and secured together made the best sounding speaker cables. I've tried all kinds of hyper expensive cables to dethrone the Downsize Audio foils ... NOTHING comes close at any price.
Downsize used a genuine teflon backed adhesive tape, double sided too, and custom rolled, extra thin foil of 6N purity. BUT he told me a person can get 90% of the same sound quality, using off the shelf inductor foils and standard thin packing tape. Try it and save tens of thousands of dollars.
