Floating ground: Any danger? Alternatives?

I have noticed that in my system even with power conditioning and aftermarket pc, floating the ground on my cdp still helps to smooth out the sound and reduce some digititis. I'm concerned as to how dangerous this is considering I've heard stories about fire, shock, insurance issues that come with doing this. Does anyone know what real risks I'm taking by doing this and whether there are alternatives that will yield the same benefits.

My guess is I would prefer to not float anything, but look for alternatives that will provide the same results without incurring some of these risks.
I have installed Hubbel outlets, clean the ground connections, a couple of Bc MkII, two Purist Venustas pc connecting to and from an AM mini digital with a Mapleshade powestrip all solely on the cdp, on a separate line from the rest of the system. Since digital is my only source, I try to clean it up as much as I can and floating the ground at the outlet still helps with all this stuff in between. I would welcome any suggestions, eventhough I've been contemplating getting into analog. My thanks in advance.
