You do whatever you feel comfortable with, but I just trust my own ears.
On your system... that's fine for you. Mine reveals things differently than yours does. I want to start off with an objective foundation if there is one. I want to know what NuPrime understands first. Then I may experiment. But first there may be advice to be learned, that once understood, will let me know what I am working with.
Certain components may have a preferred filtering to use. Some may not. But, if I have no objective foundation to work with? I may be plugging in one component into an outlet, that to my ears might be offsetting a coloration being caused by another component being placed in a less than optimal filter. If that's not the case? Then I will at least know that is so when told so by the one who knows the equipment. That's all I am asking for to find out.
I have learned in the past that there may be something that I am assuming... But, once shown its not the case? Suddenly certain pieces fall into place.
