Good discussion and I learn along with you.
Fully agree and understand both of your posts and think that you have invested in a proper solution for surge protection given the constraints of what is available in industrial power source products (or elsewhere to my knowledge).
MOVs are imperfect as you know, but at least the manufacturers of your products seem to recognize/acknowledge that they are known wear items (sacrificial in nature) and provide a warning system as they begin to fail. I shudder to think how many trusting consumers sit unaware as we write that the MOVs in their inexpensive "surge protectors" have long since ceased to provide any protection and are likely to be unnecessarily limiting current flow to their audio devices.
