This idea is growing on me.
I think it makes sense. If you grant the subjectivist position in its entirety that break-in is audible. Then further grant that the reasons can be tied to various electrical components (notably capacitors) achieving their steady state, i.e. constant, values only after a period of time. Hence, we concede the position without a fight that subjectivists are fully capable of audibly determining small changes in the electrical values after say 96 hours.
If a subjectivist accepts the above, then since they know that the values of resistors, capacitors, inductors, and god knows what else is in a player, or an amp for that matter has various manufacturing tolerances, logically they must accept that they have the ability to discern differences in sonic qualities among several samples of the same model number.
Now, given that the objectivists have fully conceded the above, the subjectivist must then realize that if they say a particular wire or cable has a particular sonic quality, then they must be able to discern differences with different lengths. After all, while a given wire may have a particular resistance, capacitance, and inductance per foot, going from 3 to 4 meters means the total capacitance for example has increased by 33%. After all, the subjectist has already emphatically stated their ability to discern small electrical changes as equipment breaks-in. In fact, it would be foolish for the subjectivist to make any claim about something as pedestrian as zip cord. They've never heard it in your system where the length is 79" and it's been broken in for 2 years.
