I'm toying with the idea of trying a balanced mains transformer as it seems like it might be a better approach than using tons of mains filtration gubbins. However, what I'd like to know is whether a balanced mains transformer like THIS for example offers any kind of protection against power surges that might damage my equipment?

I currently use some Belkin PF30 units which as far as I know provide filtration and surge protection, so I'm worried that I might loose the protection these offer.

Cheers.
