what effect does fire/heat/soot on digital equiptment?


i had a fire outside my home theater room. the heat was sufficient to melt plastics and crack windows in the room. I had a Meridian system installed. the system was about 20 years old. Is there any value to testing the components?

Its digital. Digital is binary. Either works perfectly (perfect sound forever!) or not at all. 
Soot is essentially carbon and it is conductive. I doubt they are damaged, but having them opened and cleaned, compressed air (non oiled) is generally enough.
