Very nice comparison, thank you!
(I stopped following this thread)
While I get 0.3 Ohm for TRN 3, my measurements for NiceHCK Litz is 0.5-0.6 Ohm for 3 contacts and 0.6-0.7 Ohm for the 4-th.
Within high relative error (ca. 0.15 Ohm), it can be 0.7-0.8 Ohm, but I am happy with these values, since they are within the range of several of 16-core cables; and less than 1/16 even for 12-Ohm IEMs.
I do like aesthetics and the fit of NiceHCK litz much more, compared to TRN 3 and the fit with CCA CA16 seems nice
(I actually ordered another cable for more brutal match but sadly, this cabke is still on its way for more than 2 month... while NiceHCK came under two weeks!)
