If that's your criteria for proof, then you should also have photographs of yourself in your freezer, little bags of rocks taped to all your audio gear and other assorted silliness as those things are also purported to make your system sound different.
Granted things like resistance and capacitance do matter so a crappy $1 cable and a quality cable of the same material will sound different which will complicate matters even further. Therefore a truly scientific like for like comparison isn't really possible.
If there is an actual audible difference, it won't complicate matters at all and a scientific like for like comparison is indeed possible.
Besides if you dont believe your better off, put your wallet back in your pocket and walk away. Ignorance is bliss and all that..
But when one tries to pass their beliefs off as fact, then they have the burden of proof. And in these past several decades, no one has ever demonstrated conclusively that cables produce audible differences unless they're very poorly designed or broken. And again, there's no "agree to disagree" here.
