High end UPS for Expensive audio eequipments

Without prejudice to the performance degradation issues from the insertion of the surge protector unit and its filtering effects, High-end audio gear usually already has high-end quality build power supplies that do not benefit from any intermediary plug-in surge protection or power conditioners.

if surge protection gives you added peace of mind, then only add it as a quality build system-wide insertion by a licensed electrician at the Electrical panel rather than ANY wall plug-in accessory.

the best protector is anticipating a problem; were you aware of questionable weather conditions and ignored the warning signs of a potential problem?  

were you scared enough to learn this lesson: disconnect, and listen safely later, when the atmosphere is stable

get insurance?

I have the same setup as milpai, so whole house surge protector, dedicated lines, and Brick Wall on sensitive (digital) gear. The power lines here are underground, I have stable power, but I still pull the plugs when I hear that thunder getting close.
