For the past 6 years I have had my system running through a Newpoint surge protector, and have never had it trip or had a problem with my system, (no video or audio problems). However, I have not had much trouble with the weather until this summer. The past week has been terrible with thunder storms, brown and black outs. So I am rethinking about my system's protection since I cannot be home to unplug my set-up every day. Any thoughts about the Panamax 5300 vs the MonsterPower HTS 5000 MKII? Panamax apparently shuts the system down if voltage goes outside parameters but I don't see this with MonsterPower, but then the MonsterPower has a higher joule rating than the Paramax. Oh what to do with my money?
