What does that even mean ?
Placebo is not a tool, it is an impediment to genuine understanding.
I think your above comments only serve to indicate that you underestimate the impact of psychology on audio perception and seemingly assume that you have some level of control over it.
You don't have any control over it with normal sighted listening and one has to wonder just how much of what you "hear" is real and what is make believe, despite that you think your Susvara are some kind of stethoscope into audio equipment.
How many ways and topics are you intending to find to have the same general conversation, don't you have anything better to do ?
