Whole House Surge Absorber.

I just installed myself "whole house" surge protector. I've already lost garage door opener due to line spikes last winter. Siemens style panel protector takes space of two standard circuit breakers - dual circuit breaker with built in MOV type surge arresters. Taking two spaces in my panel allows to suppress voltage spikes between each phase to ground and between two phases. Installation was very simple - placing double breaker in place of two singles and connecting thick ground wire to ground bar. Two green LEDs show active protection. Siemens recommends using it as additional protection when expensive electronic equipment is involved. I have all my gear plugged into Furman Elite 20PFI conditioner that has very tight non-sacrificial surge protection. My gear (DAC+Class D amp) is powered 24/7 but I always unplug it during thunderstorms. How do you protect your gear?
