If you leave it in the box , it will take longer to heat up because the box is semi-insulated with packing.
I would take it out of the box....but ..I wouldn't play it right away.
Moisture may have condensed on the electronics when the unit is fresh inside the room and opened.
I had a stereo amp delivered just like that last week. I took it out and just left it until the metal reached room temperature and any condensation evaporated.
I didn't like the idea of firing up a dead-cold amp that may have condensate on the electronics.
