Burn in after repair?

A little too early in "re-burn-in" to know much.  It was one channel that was repaired and I don't have the manufacturers permission to put out info on them.  They are an established high end company that I have had several units from over the years.  It does remind me of new units that I have had that did improve sonically with some use time.  Thanks 

I had $600 of recaps/updates on my amp.

Burned it in over 300 hours.

Since when did you need a manufacturer's approval, as a consumer, to either tell other people that you bought from them or that you had a repair done. This place just keeps getting more bizarre.

Manufacturers permission jusam? Since when would you need that?
