This is the closest forum that I could find, so please feel free to move it if I posted in the wrong place. I want to buy a UPS for my home theater system. I just want to be able to shut things down the right way in the event of a power outage and am not in any way interested in watching TV while power is out so run time is not an issue. I am looking at APC's Smart App Sinewave series, but see that the Smart App Intelligent series is cheaper since it uses their "adaptive" sinewave instead of a pure sinewave. Will that make a difference? The other question is that the UPSs designed specifically for HT have "high bandwidth RF protection" whatever that is. These have EMI/RFI filters. Do those serve the same purpose? I also do not want to pass any additional noise - or introduce new noise - into the system. I know "power conditioners" are a controversial topic in the audio world and don't want this to turn into one of those threads, but do these units I mention also serve that purpose? Thanks in advance from someone who knows nothing about electricity except how to plug things in and flip a switch - LOL!
