Nice eye candy though, I have the Belkin PF60. If you have a seperate amp, these power filter/surge suppressor items make it a little easier on the amps as they fire them up after the preamp is turned and allow a little delay if so desired.
So far as any actual benefit to having one is purely up to each situation, as some people have very noisy/spiky power systems feeding their homes and these products help even things out, which in theory should make life easier on the components hooked up to them, although in reality, most products allow for these discrepencies with their own power supplies containing a certain amount of suppression already.
