Default cap conditioning question

Hello,
I broke in some Black Gate and PP caps then had to leave the project for a couple of months. Now I'm getting back to it and would like to know if they should be conditioned again, or is once enough?
Also, do oil filled motor run caps benefit from this process?
TIA

Breaking them in is a waste of their life IMO, they only have a certain number of hours lifetime. Just use the equipment and they will break in on their own, while you get the benefit of listening to music

The PP caps (mostly) only need 1 time break in.

I gave up with Blackgate long time ago. Break in took ages , if you don't use your Blackgate it will need another break in again.

man i read it all over but dont think i've seen a logical answer or reason why. What exactly is breaking in caps? I mean they are built to do what they do, so what actually happens to the cap when it is broken in? Something physically changes internally? An internal chemical reaction? What?
I guess for me to understand this breaking in "theory" the cap would have to change internally, physically or chemically.


ps not trying to start something crazy debate. just want to know what happens to the cap when it is considered broken in.

in electrolytic caps, it got something to do with it's structure and chemical I guess. In case you never heard it, try panasonic FC in your power supply, listen to the difference after 15 minutes of operation.

in plastic caps, I think it's mostly healing of the dielectric.

oh new unused. haha ok, i'll do the experiment, i can swap out the caps. So your saying within 15 minutes there should be an audible difference? And this only happens once with FC's? also have you heard other caps that took longer?

never mind the last part i just reread your post about the gates

actually other panasonic electrolytics in signal path also behave the same in my experience. This might not only happens once, the longer the equipment is not used, the "break-in" need to be redone, hence my dislike for blackgates.
