Protection needed for amp?

I live in N. CA, where power outages have become more frequent.

As a result, we've had a propane back-up generator installed that comes on automatically when the there's an outage.

Question: If my system is running and power is suddenly cut off due to an outage, then suddenly restored by the generator, does this pose any danger to the amp?

My recently purchased Hegel H390 is the most expensive component I've ever bought and I'd prefer not to replace it.

If it sounds like I know nothing about electricity, it's because I don't. 

When I power up the amp, there's always a delay, then a loud click, before it's ready for use, whatever that might suggest. 

Thanks in advance!

Thanks so much for taking the time to provide an in-depth answer!

I'll try one, if I can get one with a return policy-- I'd be very pleasantly surprised if it doesn't affect SQ.

As for PG&E, don't get me started. I would say they are, in fact, very trustworthy-- they will always act in favor of  their own financial self-interest !

+1 carlsbad for explanation. I do have surge protection for my equipment, but then I've doubled to 5X the filter cap capacity in virtually all of my equipment (not just the power amps). Class D subs don't go into the surge protector.

@carlsbad:

Thanks very much for that detailed explanation. you bring up many points about which I was unaware. 

I suspect the Hegel does have a "soft start", if the short delay between pushing the on switch and the loud click that indicates its readiness is an indication.
