Furutech Gold and Copper connector

I was wondering how long does Break-in Time of “Furutech IEC connectors” takes in order to open up and present all its potential quality. I am talking about Furutech FI-11 Gold and Copper connector series. The power cables where connectors are used with, are already broken in and sound good with their original connectors. I read in several review that Furutech cables takes up to 400 hours to break in! Is this also valid for Furutech connectors too!?

You feedback would be appreciated.
cheers,
Michel
