Defeating a three prong power cable with a "ground lifter" etc., is not only dangerous, it defeats the UL listing (Underwriter Labs is an independant body which tests electrical devices for safety under extreme conditions), and will invalidate ANY and ALL insurance claims that occur as a result of that equipment. The ground is there for a reason (aside from causing ground loops): in the event of electrical fault within the equipment (caused by internal or external forces), the ground acts as a safety to safely shunt excess current away from the chassis and you. Solve your hum problem by finding out what is causing the hum in the first place.
Ungrounding an Amp--Any Danger?
My integrated amp, a Creek A50i, has a bit of humming. I was about to experiment with removing the ground from my power cord when I saw the sign on the back of the amp that said "This apparatus must be earthed."
Is there any danger (to me or the amp)associated with removing a ground? I will gladly put up with a bit of hum if it means not getting shocked or frying my equipment.
