Teo, I'm not sure what stone age you're from. Not only can we measure the movements of electrons, we can measure their spin. We can most certainly measure the motion of atoms with more precision than the human ear. Just because you don't have the tools to do it with doesn't mean it's impossible. The entire reason we invent tools of measurement is because these tools measure with greater precision than our senses do.
Who cares? Measurementalists are free to conduct their own tests.I'd expect this kind of mindless quip from you. The OP asks a very rational question that clearly went clean over your head. How do you properly pair components if you don't know what the measurements on them are like? I suppose you'd suggest "Go blindly groping in the dark and sample all the snake oil for yourself" rather than use some basic analysis to narrow your options.
