Perhaps. But it reminds me of a favorite adage I often cite about what we learned in med school.A power cable is not fundamentally different from a signal cable. Looking from a spectral perspective we do not expect the difference due to burn-in in power cables to be related to the 50 or 60 Hz component, so all we will have are differences due to how it handles noise. The same for signal cables - if the differences due to burn-in showed in the audio band - 20 - 20KHz - they would be easily measurable. So probably we are mainly dealing with something going from the hundred of kilohertz to a few gigahertz when addressing burn-in. A real nightmare!
"Half of what we learned in med school isn't true. The problem is that we don't know which half"
