[QUOTE="jeallen01, post: 1015902, member: 176704"] The photo shows the "concentric double squares" printed on the back of the Rx which means that it is safety Double Insulated (technically called "Class II", and that's not the US "Class 2" which is entirely different!) and does not need a protective Earth/Ground in the mains leads. Don't think that a mains lead with an Earth conductor would cause hum issues -, but, OTOH, I have had to add small earthing conductors to my mainly Class II AV system - with, then, a connection to the supply mains Earth pin in a mains plug - to eliminate hum issues! Also, when you connect a lot of Class II together you can get quite high collective leakage currents on the chassis of any of the units, which can give you quite a "nip" if you touch it and "true Earth" (such as a c/h radiator) at the same time - the small Earth connections I add do however eliminate that! :D Therefore, in any country (could be Israel??) where there are a lot of un-Earthed mains outlets, I recommend the same small Earth connections solution, having connected the lot to "true Earth" (in a socket or a water/ c/h pipe).
