I'd like to protect my gear with either a ups or power conditioner. I've seen a couple of threads about surge protectors, but nothing else which weighs the advantage of the other 2. Some of the electronic retailers really pushed certain products which tout 'filtered' power. Do not both ups and line conditioner have stability built in? Which is better for HT? MY power requirement are not high, perhaps under 10 amps most of the time using HT receiver, subwoofer amp, 27" TV, and either SAT or DVD simulatneously. Rarely doesn anything get turned up over 30% of volume. Thank you.
