added cable 066 to my list of cables measurements: jcally, silver plated 5n ofc copper, 8 cores, zsn (c-type) termination. and measurements of zsn (c-type plugs) version of cable 065 (4 thicker cores).
also found in other colors and terminations.
nice conductivity (equivalent to ~24AWG thickness, around 128mΩ/signal).
sound is good enough for not very resolving iems.
found two issues:
1- jack (furutech cheap styled) is low quality (like in cables 065 -jcally- and 056 -trn-). found a core (L+ in this case) unsoldered or not well soldered. it's the second jcally cable (and all 056 trn cables) where i've found this issue. maybe there is very small space to solder, who knows.
2- this zsn version has got inverted polarization respect KZs norm (both sides); i.e., sign signal should go down (hole at the extreme of the shell), but it goes up (interior hole) in both sides. found same issue at cable 065 (jcally), zsn version, as well.
as both sides have same polarization, they won't be out of phase, and sound won't be affected. but being purist, i'd prefer right polarization, not inverted.
if you get curved 2pins plug, like these zsn type plugs, there is no way to set the right polarization without re-soldering the plugs.
