For general consumpion. EVERY part that sees duty in any of my products is cryogenicall treated for 48-72 hours before I use them. I get them in - they go to the cryo oven. It's like chicken soup - couldn't hurt for what ails us.
Breal-in is a strange phenomenon and it varies greatly for different components. Some are broken in in a few hours, some take hundreds of hours. Much of this has to do with dielectrics in play. PVC b reaks in the quickest, teflon takes the longest. I have not been able to make a decision on wool, cotton or silk. Airbound dielectrics seem to not have any break-in time. Makes sense. That is why I use organic fiber dielectrics whenever possible.
Rhodium is your bi-polar, paranoid schizophrenic junkie cousin. Takes forever to break-in (300-600 hours) depending upon application. It does have some great attributes like clarity, low noise and dramatic dynamics. We travel quite a bit to see our family. I have found that the GTX(R) NCF will regress over the period on a couple of weeks and then go through a short break-in when we return. Bercause of this I plug 40W lightbulbs into those receptacles when we travel. Keeps them happy.
Audio, my friend, is weird and so are we
