When you plug things directly into the wall in hot pursuit of...."dynamics" n all... you may end up with no gear left, no music...
Try to plug things into a good power conditioner w/protection features enabled.
I do like my furman 20 I. In the west we have many power issues and so far it has been good to me. It has an extra 60 amps in storage capicitors for transients in big monoblocks.
Sorry to hear about the power issue. Good advice re checking the responsibility of the power co. and also on insurance.
But for those with surge device recommendations that's good and we have whole house protectors on our 2-Mains panels and downstream rack mounted protectors; nevertheless, I'm presently working my way through a nearby lightning strike damage.
Low voltage, integrated circuits were mainly effected (a digital streamer and HDMI circuits on two preamp/processors, along with the modem (it was still working but having periodic latency issues), a 24-port switch & router etc.
The assumption is that the surge mainly came in on the Ethernet coax line. But our WIFI irrigation controller was affected and it wasn't connected to the Ethernet and a ceiling fan (with a DC motor) on a covered deck was also impacted, but only when run on high speed. When on high, a thump would be heard, the fan would slow, but then run back up to speed (wash>rinse>repeat). It seemed like some sort of overload protection circuit was kicking-in -- weird stuff. Everything else A/C wise is fine!
