We get those from time to time up here though mostly because of critters getting fried in the transformers. A UPS is a great addition, to any system , possibly the best thing you can do for your equipment . I think originally marketed to computers they are great for modern AVR's and Pre/Pro's which are essentially computers now, mine runs linux. Anything you do really to protect your valuable equipment is a good idea really, none of these things do any harm thats for sure. I take issue with statements that imply they make things sound better.
