From watching the cardas video and having owned some of their cables, I doubt you can get that type of crimp by hand...unless your using some sort of manual hydraulic jack. That's heavy gauge wire and a serious spade....Hand hydraulic crimpers have been around for decades that are almost the same but with more capable higher pressures. Actually enough to crush that terminal to pieces. Don't forget, that is soft copper. That crimp won't pass inspection for a lot of aircraft crimps. I wouldn't want to be under any high voltage power line with that crimp. They use portable rechargeable crimpers for up in the air that have a lot more pressure. Here some links with their specs. Simple math. Old technology. It's been powering the world literally. Aircraft, cars, and an endless list before hi-end audio cables. In his video of the cutaway, you could see a lot of air gaps, that shows it could have been better. Again, nothing new. They might sound good though.
