Kitjv, regardless of what you get or try, I would strongly recommend that you compare your sound with and without it. I suspect you will remove it.
Remember that you can always unplug your system in storms or when you are out of town. My house has been hit by lightening twice. Once the system was on and plugged into a Sound Application unit. Nothing happened to my system or the Sound Application. Once my stereo was off and plugged into a computer surge protector as was a computer. The computer and the surge protector were wiped out but the system was fine. Obviously the surge protector did nothing for the computer. I guess you can take this as a recommendation for Sound Application. It is still made.
