My knowledge of Physics is average. I am sure there are many here who have probably heard of this experiment,  called the double slit experiment.

Atoms are both particles and waves until they are observed

This  had me thinking of our electronic gear ( Cables ) etc measurements how ( two cables can be measured and show know difference  )
Two amplifiers can be measured and show same spec thd , harmonics , power signal to noise ratio etc ) all those things they can measure.  yet sound completely different
So when we are measuring ( we are observing so the atoms change ) and when we just sit down to listen the atoms change  :walled:

So all the debates about cables not making a difference  cannot be answered by engineers simply because well they are not physicists  :ROFLMAO: and their equipment is probably measuring the wrong thing  :thinking:
