I totally agree with erik_squires and dpop .
I had my system connected to a Tripp-Lite when the neutral wire to my building broke sending 240 volts into my building , burning out 2 refrigerators , exploding light bulbs and taking out the Tripp-Lite which saved my system from any damage .
I now have almost everything in my house connected to a Tripp-Lite Ultra , but I still have the amp connected directly into the wall due to the current rating of the TLU.
