Try some citrus based wood cleaner.

I'm afraid you're screwed. Rubber and many like products do not play well with wood finishes. Seems to be some type of chemical reaction which melts the rubber and fuses it to the wood finish, ruining the finish and even the surrounding area. Bummer. Ruined a nice sideboard cabinet top with some stupid rubber-like feet on a stupid amp stand. Now if I have to set feet like this on wood I put a small piece of packing tape on the bottom of the feet to isolate the rubber from the wood finish. You'll need to refinish the entire surface. Bummer.
Ronsonal has no effect on metal Dopogue (or did you mean the Vibrapods etched the surface?) Anyway, the 'metal' surface must have some kind of coating on it. Some of these clear coats are resin (epoxy) based and will absorb the solvents in sorbothane (or from rubber feet, if you stack other components on them.) Don't know why this happens with these clear coated surfaces (as opposed to painted surfaces) but it often does.
If Vibrapods are sorbothane, they are a highly plasticized polyurethane, not rubber. Most polyurethanes will leech out plasticizers and oils over time. The goo will actually melt certain classes of thermoplastics. (It happens in our lab when parts cast from some highly specialised polyurethanes get set on a sheet of polystyrene and left for a couple of months.)
Use low density polyethylene ("Ziplock" bags or similar) as a buffer under the feet.
Also kerosene, charcoal lighter (naptha), or maybe Bestene, will remove the residue. Nothing you can do to fix any topcoat or remove the stain if on wood except refinish.
