The end results for the ears being the only irrefutable proof or experience because no set of measures can tell all the story in advance...
An experiment:
If i put a piece of quartz or a piece of shungite on the central electrical panel of the house or on the transformer of an amplifier, where is the set of measures that will tell you the differences between these 2 operations at these 2 different locations and why?
My ears has told me the end results, if you want to know it, you must realize the experiment.... Even if no audio manual describe this experiment, it is a possible experiment with an end result....
Just a clue: there will not only be a variable audible effect in quality,( variable relatively to each house and each audio system) but it will be different for the quartz and the shungite, but the quartz will work the same in the 2 locations and the shungite too, confirming their own particular different power to increase or decrease the S.Q. end results for the ears...
By the way i dont sell nor buy anything, all i made are my own homemade experiments....What is the essence of my 2 last years experiments is not the purchase of a bunch of costly ready made tweaks, it is a systematic method between experiments and listening with only cheap materials and homemade simple device....
And for those ignoring the placebo methodology, an incremental, step by step positive increase in audio S.Q. extending in time with many experiments is no more a placebo, then it must be an hallucination.... But if you say that, then all audio experience is pure hallucination and even the concept of sound quality or S.Q. is a snake oil concept, and audio engineer dont need their ears no more now, only oscilloscope, db meter etc...
By the way i want to debunk the myth that Hi-Fi experience is linearly linked to the big money invested in the new electronic design component around the block....
I dont say that cables or new refined electronic design dont do a big difference, i only say the essential is not buying disparate costly tweaks, or costly cables, or costly electronic components; the essential is listening and learning how to embed in his 3 dimensions ANY audio system at any price, to make it able to work at his optimal potential....
I want to debunk the "upgrading" urge and myth as solution to audio problem and experience....

My best....
