@mclinnguy ..Got the cables back from Cardas yesterday. They are now certified and have been re-terminated with updated sleeves.
I've had a few older pairs reterminated a few years back, and not only are the ends a little different, the newer process to apply the termination is different too. Was informed beforehand this changes the end result with a little more resolution across the entire frequency range. Some of the older cables with a stiff outer jacket and dielectric inside do change a bit after they are uncoiled and set in place for more than 14-21 days.
George Cardas talks about tension release and some info about any type of static electricity that goes away over time, after being set in place and played for a while. I've retested this theory several times with reintroducing old cables coiled up stored away, and multiple pairs of brand new day-1 vs. 60 day used cables, swapping them out for the next new pair of the exact same cable, and having to start the process all over again. The newer version (more pliable) cables seem less effected compared to some of the old version (stiff) outer jacket cables, or the ones with a stiffer dielectric inside, I don't know. In all cases, I always give it the first 14-21 days, taking notes, and listen again at 30 days to compare fwtw.
