Measured with? You would probably have to measure the frequency of each harmonic within a
few hertz and the amplitudes within 1db or less. I was surprised, after many years as
being a technician, how little the change was required to make a huge difference in sound.
No magic wire theories, but there are changes that fall in the tolerance ranges of test
equipment that can be heard by the ear. It's amazing what the ear and brain can interpret
(and misinterpret).
