But kosst, why does it matter to you ?, this proof thing. I use my ears. When I change out a piece of gear, a cable, different footers for my transport, fuses, whatever, I decide if I like it or not. Obviously if I hear no difference, it gets sent back. When I do hear a difference, and I almost always do, I live with it a while and determine if it is an enhancement to my system. If I find I enjoy my system more, great. I keep it and pays my money ( or I might try something else ). That’s it. Nothing more, nothing less. Many of us here on the Gon, and elsewhere, share these findings with each other. And then, you come along ( and I know you are not alone ), and do what you do. Why should it matter to you ? When many of us hear these differences, science becomes less important, unless we want it to be. But we are who we are, and it is what it is. Science is your thing. I respect that of you. But, if you do not try some of this " snake oil ", as you put it, then just leave it alone. You are not god, that we need to provide you with proof. BTW, I am on a limited income, but save for my audio toys. Always, MrD.

 I tried to be civil and not rude, however I don't think it is rude to request scientific information for products with these crazy claims. I have built somethings and feel I have a bit of a grasp of the technical side, so some of the claims just make no sense whatsoever.   It is OK to be challenging, that promotes learning. The challenge lies in how to be challenging without being rude.   

 And for the record I have tried aftermarket fuses and used to believe and magical wires and so on… Until I learned more about how things worked and learned that many of their claims were literally an impossibility.    Everything in the world must conform to the laws of science so I think it's perfectly reasonable to ask for scientific explanation for some of these items and claims.   
 Many of these believers would benefit from some reading into expectation bias.  When you think you are hearing a difference many times you simply can't trust yourself. I myself would want to know the truth and not want to bury my head in the sand  while spending thousands and thousands of dollars on items that do literally nothing.  
 The long and short of it is I think many just cry foul when their sacred beliefs are challenged in anyway.   Granted I do see rude behaviour on the forums but it comes from both sides of the fence. 

Oh, brother! Bring out the crying towels! It’s cryin time again. 😢 At least perhaps most the anti tweakers and defenders of the sacred Laws of Science can be corralled in one place, at least temporarily.

@mrdecibel I think kosst explained it perfectly. Whatever we write is now up in the forum for all to read, many looking to learn. Then these newbies end up taking this stuff as Gospel. That's why kosst and I feel the need to shine the light of reality on some of these discussions. 
Plus i hate the idea of companies essentially  ripping people off, selling them stuff at a 2000% markup saying it does xyz when it does nothing. 
It always boggles my mind that we have these fuse threads that run 50 pages of nonsense but if you start a room treatment thread, stuff that works, makes a difference that you can measure, you will be lucky to get one page.
