This may be a stupid question, and forgive me if it has been asked already. If your HT speakers were brand new out of the box, when you had initially ran YPAO on a Yamaha receiver, and speakers are said to "break in" or "open up" after a certain period, should you after a few months of this break in, then re-run YPAO, and also, if you have added a new piece of furniture to the room in addition to the existing furniture that was there when YPAO was first run, should you re-run the calibration? Thanks in advance!
