All of the Running Springs Audio products would apply. They can be used anywhere on the planet. They are also non coloring and non current limiting. Visit www.runningspringsaudio.com.

thank you for suggestions. some people claim this coversion will make the audio units connected sound worse, or at least not as good as if the powersupply in each unit is rebuildt.. any thaughts?

Hifimannen -- I think the people at any of the manufacturers mentioned above would be candid in saying if doing what you propose is not the best way. They have nothing to gain by creating a dissatisfied customer. I would definitely call them all and see if there's a concensus.
