Surge Protectors
SurgeX is the technological leader in surge protection for the residential market. Series-mode with non-sacrificial components means that it doesn't slightly wear out with every little surge like cheap MOV-based units do. They also don't choke down the current in the same way either. If you plan to plug an amp into a surge protector, this is what you need to be looking at. A surge is loaded up then safely trickled out via the neutral wire instead of shunting to ground which is much safer with sensitive electronics. Everything about them is superior to your cheaper MOV-based units.
