I'm looking at an upgrade to my theater receiver for the first time in about 5 years. While perusing the various products I'd be willing to try a lot of the online sites tack on 'recommendations' that include the Monster signature series of power conditioners. Are these things worth it? They're between $399 and $999 depending on what ones you get. Panamax is another one listed a lot. I've not suffered from a lot of power problems that I know of, but I've also moved to North Carolina from KS. There seem to be a lot more 'power flickers' here than there was in KS. I'm sure it has to do with the abundance of trees here compared to KS Any suggestions?
