Lots of great advice so far; but, here's some first hand experience to consider...
Many years ago my house took a direct hit by lightning and it fried many things, including my Sim Audio amp. I took it to a local Sim Audio dealer who then sent it back to them (in the original box). When it came back it sounded significantly better than before the lightning strike; so, make of that what you will.
