@stephenjfoster For some reason you seem to think there is an element of religion or faith involved in any of this while forgetting that science is based on observation and experience. Now I agree with you that subjective experience should be viewed with skepticism. And a simple model of electricity would assume that LCR (inductance, capacitance, and resistance) is adequate to explain how cables work. That would suggest that all cables with identical LCR are the same. In fact, there are all sorts of credible explanations about how changes in the geometry, materials, shielding, and quality of construction can impact the signal. Figuring out which, if any of them, are true isn't something I care about.
I started the journey buying spools of 12AWG OFC copper from Amazon. It is only my experience based on years of critical listening and hundreds of level matched A-B comparisons that ever caused my hard earned dollars to be spent on anything as frivolous as cables.
For me, the bottom line is even though I am not religious, if God appeared before me you can be d*mn sure I would change my mind and become a believer (after checking for mental illness). You could discount it as my subjective experience, in the same way you discount that cables can make a difference, but for me it would simply become a new fact about the world.
You might want to spend a moment on self-reflection. You aren't an audiophile and you haven't posted any information that any well educated person who has spent a week in this hobby doesn't already know. For some reason you made strident and insulting posts that assume everybody else is stupider and less informed than you are. Maybe your ex-wife is right?
