Kit and cable burn in
Just occurred to me there is a way this can be tested.
Needs a lot of kit and some diligent record keeping
Take 2 (or more ?) of the brand new item to be tested, identical age, batch etc.
Use a stable system that will have no other items changed
Use the first for a fixed amount of time to be agreed in advance.
After the time has passed take a second brand new one and compare it to the first that has run in (or not)
Put the second away again
Play the first for another agreed time.
Bring back the 2nd and compare
