Wow, your comprehension really is very poor. In the absence of any substantiation, the phenomena (perceived differences between electrically identical cables) is most commonsensically presumed a placebo/expectancy effect, rather than something in need of dis-proof. Clear enough for you? In other words, give the cable sceptics (who are, after all, in the mainstream as far as scientific knowledge goes) something substantiated to disprove, rather than postulating an effect and then demanding they provide evidence to show that it's not entirely in your head. This is ABC stuff.
