A friend of mine recently told me that he uses an APC UPS in his home theater instead of a monster surge protector or line conditioner. The UPS works like a battery pack for your HT. The system works from the battery and the direct current so you always get a steady consisten power stream. And if there is a power surge... there is no interuption in power. I live in an area where we get constant power outages and surges. I bought a Monster HST2500 but that doesn't help with the equiptment turning on and off multiple times within a five minute period when the power keeps fluctuating and it doesn't help with the "brown-outs" when the power doesn't go completely out, just dips and spikes. Have any of you used this in your setup? What voltage UPS would you recommend?
