What I wonder is how many of those who have experienced significant sonic improvements by upgrading jumpers have gone back and forth two or three or more times between the original and upgraded jumpers, to verify that the improvement was not simply due to differences in contact pressure, or to extraneous variables such as equipment being in unequal states of warmup. And if prior to performing the comparison a good contact cleaner was used to assure that oxidation on the surfaces of the original jumpers was not a factor.
