break-in method affecting sound of a component

there are three ways of breaking in a component, assuming you believe such a phenomenon exists.

you can input a signal gradually. you can feed a continuous signal for a number of days or you can connect the component into an electronic device which facilitates and/or shortens the break-in time.

i had an experience breaking in interconnect cable where i compared two methods--a continuous signal vs a break-in device.

i preferred the sound of the cable just feeding a continuous signal relative to using the break-in device.

has anyone treid different methods of break-in and compared the results using different break-in procedures ?

does anyone have an opinion, pro or con as to the use of break-in devices as opposed to not using them ?
