The Shunyta Hydra works with any voltage. I use the Hydra in a 230 Volts country - plus, since the Hydra has US plugs, you can continue using your existing power cords between the Hydra and the gear. You need either a special cable between the wall outlet and the Hydra or an adapter plug (not a Voltage converter). Go for the native cable if possible.
Audio Magic Stealth is available in 220 V-versions, too. Interesting seems to be a power conditioner from DeZorel in Belgrade (www.dezorel.com). German companies do make good power conditioners for 220 V, e.g. Burmester, Audioplan, Einstein, Dillenhoefer (www.dss.com)
The Ensemble Isolink is the best period. it will feed both 110 and 220 volt equipment. Call Perfect Note Audio at 508-366-2023. The owner, Jon Robbins, is currently running 220 volt equipment from one.
