IMHO, a sign from God telling me to upgrade is a large deposit in my bank account from a Mr. Yeshuah ben Yaweh with a personal note telling me it's time to get Revels and some really nice separates with blue lights and gauges. Oh yeah, that and get a new freakin' house with decent wiring to put it all in.
A power surge that I allow to destroy my equipment (be it from lightning, and unstable power grid, or bad wiring) is something I would interpret as God saying "Buy power protection next time, dummy!"
