Are manufacturer AC cables good enough?

@ cleeds, turnbowm 

No, disconnecting the ground conductor at the EQUIPMENT end, as I specified, does NOT create a safety hazard.  However, disconnecting the ground conductor at the wall outlet end does indeed create a safety hazard!  A bit of research into equipment grounding techniques will explain why.

Some audio equipment now comes with a workaround for the UL power cord grounding requirements:  you may have noticed a "ground lift" switch on the rear of the chassis. Toggling the switch to the "lift" position accomplishes the same thing as disconnecting the green ground conductor at the equipment end of the OEM power cord. 

My new Anthem STR came with a two blade plug and two blade IEC connector on the amp. It has the CE, RoHS,FCC , cTUVus, certifications on it. In case you don't know the cTUVus is a direct replacement of UL and CSA marks.

glupson, your question would be best answered by you're researching a little bit of electric power distribution history in the United States.

I don't know how old you are, but there was a time when there was no such thing as a three prong plug or a three hole receptacle.

During the transition, many folks received mild electric shocks ;~)
