indygreg,
Whatever you decide to do, you need to prevent this problem in the future. Does your amp or receiver have in-line speaker fuses? If so you may want to size them appropriately. Since the ST's are 4 ohms, a 5 amp fast-blow fuse would allow 100 watts. A 4 amp fuse would allow 64 watts. Either is probably plenty as no one ever listens to "continuous power" anyway. If you don't have any type of fuse protection, I'd seriously consider adding them. The ST's are just too nice to abuse. I'm sure you wouldn't want to go through this exercise again.
