I'm going to be getting a new TV soon (Samsung 61" HL-S6188W RP HDTV) and my brother's telling me that, in addition to the surge protector/UPS I already have my stuff hooked to (Monster UPS 500), I should invest in a power conditioner. Now, I understand what the purpose of such a device is but I'm uncertain of the necessity. I don't have a super-spectacular setup -- just the coming TV, my Toshiba HD-A1, and a Panasonic SC-HT40 "Theater in a Box" sound system. Any thoughts/opinions on the this? I'm willing to spend the money if it'll give me some tangible benefit but I don't know much about such things. Thanks.
