I insure my collection in a separate policy my primary insurance broker shops for me. Every couple years we move around, but obtaining insurance has not been a problem. It is a policy similar to what would be used to cover fine art.
Insurance for system
I have been trying to get theft coverage for my system without success. Between the electronics, cables and add ons I probably have around $100K invested in it. My broker suggested that she might be able to get coverage for some of the gear but not all of it. I know that there are specialty carriers for collectible cars but is anyone aware of insurers who specialize in coverage for what most carriers would consider luxury goods?
