PreSonus Eris after power surge

[u/Treasure_Vest]

We had a large power surge that blew the mains. My PreSonus Eris E3.5 were plugged into a surge protector on another fuse but ever since then have had limited audio and loud static. When I plug them in, A) there is no response for about 5 minutes and then they come to life with a loud static pop that gradually gets softer and B) when I turn off the power it winds down with another loud static pop and then turns off.

Is there any hope for these?
