You have no proof that painting that cable, or lifting it up on blocks, or burning it in, or switching it with another makes any difference at all. You only have claims.My listening methods and experiments are not ADDING "tweaks" after buying something...
The three things you listed here are NOT my propositions but claims always discussed in all audio thread beginning with Abel And Cain....True or not, i dont even know for sure...
I propose myself simple experiments in the mechanical, electrical and acoustical dimensions... I called that controls over working embeddings dimensions not "tweaks"..
My controls devices are not secondary addition to a system, they are more powerful than the system upgrade itself...
I learn only one thing in audio: tuning a system is more important than buying a system....
I am not in a cable obsessions club either nor in the "skeptic club" but in listenings experiments...
