I have noticed recently that more and more components are coming with two prong AC power connectors to eliminate ground loop issues. Since there is substantial discussion about after market power cords and electrical noise in this forum, I wonder if this trend is being considered. Seems like an expensive power cord with layers of shielding would be nullified by a two prong power connector because one side of the shield would not be terminated to ground. Its been twenty years since my last transmission line class but I think an unterminated shield acts more like an antenna than a shield. Can anyone comment on two prong AC outlets for Home Theater equipment and their effect on cables and noise? Also, can someone tell me how the manufacturers of equipment with two prong AC connectors are grounding the component chassis?
