Of course.Agree that basic science -could- explain perceptible differences, but you gotta know what to look for to be able to apply basic science.
They can react differently - most will. Ditto for all external params.For instance, under the influence of an external EM field, do same-value components with different composition react differently?
But if you get back to one of the subjects in this thread and take two nearly identical wires (same gauge, number of strands, overall construction, etc.), one using plain copper and PVC the other silvered copper with PTFE, the latter won't sound brighter. It'll sound the same in all proper double blind tests! Ditto for caps and most other components.
