We live in South Florida; when rain is abundant, ants will inevitably find their way inside the house for a brief period. Yes, we have pest control service, and they've already been out, but this time the ants decided to roam all over my hifi rack. Not too many, but enough to catch my attention. I've wiped off what I could, but every once in a while I still see one right under the grille of my SR-009. I've since relocated the phones, but the question is whether I should worry about anything, such as an ant getting stuck between the diaphragm and the stators, etc.
I haven't listened to them since, just in case.
