Hey guys,

Maybe I should have investigated more thoroughly before buying, but I'm basically just using a big UPS with automatic line regulation to protect my home theater. I don't have any problems with gound loops or unwanted noise in the system, just grotesquely unreliable power.

We get brown outs ALL the time, especially during summer for some reason. They'd always cause the PC to reset and the home theater to pop and the TIVO to reset. A UPS fixed the PC so I figured a bigger one would do fine for the home theater. I've got everything but the TV running through it because it's a pretty big load, relatively speaking (and it's a good excuse to upgrade if it goes ).

Anyway, I was just wondering if I'm doing the right thing or if I should be getting something like the 5100. Since I've installed it, I haven't had any problems but I just want to make sure I'm not just tempting fate.

I read through the link gonk provided above, but I didn't see anything about protection from short duration undervoltage conditions.
