Who has AC umbilical cable for SB upgrades?

I have to be careful here. My last attempt to start this thread was axed by the Agon patrol. I guess my mentioning the name of a certain company was not to their liking… Therefore, I will refrain from mentioning names (not sure why?). I am looking for a replacement/upgrade to my AC power umbilical cable that connects my Channel Islands power supply to my Logitech Duet receiver. I am aware of one “unmentionable” company who does provide such a cable replacement. Because of the negative things that I have read about said unmentionable cable provider, I prefer to find an alternative source.

I heard through the proverbial grapevine that said unmentionable cable provider markets an all silver umbilical AC cable.

Anyone know of other sources for similar cable products???

Thank you.
