the problem with break-in devices is that they provide a signal different from a music. thus the sound of the cable will differ after it is "burned-in", with one of them vs passing a musical signal.
also consider the current requirement of the component receiving the cable. burning in a cable with a low current source for a component that has a high current use, e.g., an amp, will create a different result than providing a signal from a high current source.
thus, i have been told to connect a power cord to a refridgerator to burn it in for use with an amp.
