Surge protection

Surge protectors can be very, very bad for an amp's performance and aren't generally good for low current components either.  Just about all of my important components have custom power supplies.  BTW, many surge protectors will not protect against minor over voltages that can cause bad damage.   

I use a PS Audio PP10. this is a power regenerator (much different than a conditioner or a surge protector).  

If the surge was lightning, then that is an act of good.  Sometimes your best bet is to unplug during a storm.  

If it was a human error you may be able to be reimbursed for your damage.  I work for a utility and it is not uncommon for a utility to pay for damage to refrigerators etc if, for example, 220 volts gets hooked up to a 110 circuit. 

If it was your apartment building's fault they should be held responsible.  You may have to question their explanation to get to the bottom of it.  

The good news is that human errors are often corrected after they happen once so the same thing shouldn't happen again.

This is where I went.  Professional install external to the box by my longtime electrician.  Doubtful it is the only solution, but it is a solution.

Sorry for double post, didn't mean to.  Cheers

The best sounding, and best performing for surge protection devices I know of are Furman with SMP and LiFT. I live in a lightning prone area and based on testing done by Wirecutter and my own listening tests I can honestly say I would never run an audio system here without a Furman.  Keep the feature list in mind though.  They make dozens with a variety of combinations of features but the one's you want are LiFT and SMP.

If you were in a home I would also recommend a whole house surge protector in the electrical panel, preferably one made by the panel maker that fits in place of breakers.
