I let my system warm up for a few hours every time with something playing at a very low volume before listening.
For the cables that haven’t been used for a few months, I would allow 24-48hrs of play time. Go by what your ears tell you.
Do dormant cables need "RE" Broken In? If so how long can they sit dormant?
Personally I believe new cables need a break in period, if anything, for my ears to get used to the sound difference.
One buys a vintage cable that has not been used for years (My Case), A cable in storage, or a current cable connected where one has not used that component for some time..................how long can a cable sit before it needs "re broken -Iin" or does the initial, new break-in is all that is needed for the life of the cable?
Just curious if there are any rules of thumb amongst cable experts.
