Okay, you've got me. I asked the cable manufacturer of the cables that I use, if they'd terminate the large 240VAC (30 amp?) Hubbell twist lock on my power cords. I'd sent them a pair in boxes and they returned installed on 2 separate power cords. I guess that I'd have to agree with the issues regarding IEC connectors, they are the weak link. I'd love to see something more industrial used, even heavy arc welding wire connectors, but it isn't user friendly. Many of us do us overkill wiring inside their listening room, my electrician thinks that my friends and I are crazy. Oh well, it did make a big difference. Every time I think about home wiring, my memories are drawn back to the old Sahara in Lost Wages where we use to have Winter CES. Everything was done to code, but with all the exhibitors, you were sometimes lucky to get 100 VAC at the wall socket.
