There exist so many points in the complex grid encompassing the audio system in each house that only incremental step by step controls methods, using multiple ways in its 4 dimensional embeddings, can gives to each of us the solution to a greater S.Q.; an upgrade S.Q. without any purchase of a costly electronic component for a fraction of the price.
I read an article about a 40 thousand dollars P.C. USB server and dac, and comparing the same musical files in my P.C. with the impressions of the reviewer, gives me the feeling that the gap between this marvellous piece of engineering and my humble audio system, but very tweaked and controlled installation, was not an abyss... Most people underestimated the noise level on their house electrical grid and think that upgrading for example the conditioner will solve the problem, or purchasing a miraculous power supply...All that will give an upgrade decreasing the noise level, but introducing a noise of its own....
The law of diminishing returns is way more lower than most of us think when we address the embeddings of our audio system the right way, without introducing new electronical component with their own noise level ...
There exist NO electronical component that will not contribute in an higher noise level.... It is always a trade-off...This is the reason why " non electronical way" to act on the electrical grid is so impactful....Personally I choose the passive ways with stones, especially my "golden" plates....No trade-off in the noise floor....
I am astounded by the fact that the S.Q. we lost, unbeknownst to us, because of a too much higher noise floor, is totally out of our consciousness like a blind spot... It surprise me each times when I lower the noise floor, because it is an incremental step by step process, no miracle here....
Perhaps going off the grid is the way, but the cost are way too much for me now to try it....But even battery introduce noise then my "golden" plates will be useful there also....
