Lumagen Earthing?

Hi, my Lumagen HDP is causing a ground loop hum through my new ATC active speakers. As the Lumagen is an American bit of kit I pressume its double insulated so therefore can I disconnect the earth in the plug to eliminate the ground loop? I have done this before with amps built for the american market which only require a live and neutral connection:)

Cant seem to find it, have tried about ten different words relating to hum, audio, ground loop etc:confused:

Thunder, could you run a separate earth wire from the Lumagen to wherever you have the speakers conected?

I dont believe that the Lumagen itsself should need earthing as our cousins over the Atlantic only use two pin plugs. But Im not sure about the offboard power supply supplied with Lumagens in the UK:confused: It would be really easy if I could just disconnect the earth in the plug:)
