Geoffkait 3-28-2017+1. A good audio-related example of that can be found in the current thread entitled "Most Important, Unloved Cable," in which several people reported that significant sonic improvements resulted from upgrading ethernet cables that are used in their systems. With the upgrades in most cases being very inexpensive.
... most or almost all observable phenomena CAN be explained by current scientific laws or facts. What might be difficult for one person to explain might be a snap for someone else.
A couple of posters, including one who deals with ethernet networking professionally, dismissed that as preposterous, and undoubtedly the result of expectation bias. But for someone who happens to have the right background (me), it was a snap to explain those results. And to explain them in a manner, as I put it in that thread, that is "well within the bounds of established science and engineering." See my post in that thread dated yesterday, 3-27-2017.
BTW, in saying this my intent is certainly not to toot my own horn, but simply to provide a specific audio-related example supporting your comment.
