I think it's best to break-in ICs in the system. And as most people seem to agree, if you remove them from your system for any length of time, or change their orientation, you'll have to break them in again anyway. I think maybe PCs can be broken in before sale, I'm not positive on that one.
Components, SS and especially tube, should be broken in by the manufacturer, I agree. It would not only improve sonics out of the box, but quality control/reliability as well. It will add to the price, so it can't be provided for modestly priced components.
