better sound after big power failure?

Wednesday was getting ready to put the Wall into the player hit the open drawer button and the power went out for about 1 square mile anyway was off for about 6 hours this happens about every 2 years in this neighborhood anyway must be something significant that failed I would think and needed replacing anyway next day play the system it sounds absolutely spectacular the dynamics were especially strong and quick and bass was punchier the midrange sounded more clear than usual also. So was this just a coincidence or was Edison just using old [bad sounding] worn out parts which just died and got replaced with new stuff?
