Cryo a power cord?


I have some MIT Oracle AC3 power cords. 6 ft each. Has anyone experience with cryoing these cables. I find them excellent as is, but curious. Thanks.

I've had great success cryoing various types of interconnects including power cords and in each case after a ***long*** break-in period  there was definite improvement. I had a conversation with Alan M. Kafton / audio excellence AZ, INC. and we discussed some items you don't want to cryo.
I'm not sure what kind of electronics are inside of the box, but you might contact Alan with that question.
Most hi end cables are cryod. They couldn’t compete otherwise. A lot of them don’t advertise it, you know, given how suspicious a lot of audiophiles are. They want to hear the pure sound of the cables. 😛
