my wish has been granted!
8 cores cable of taiwan frozen up-occ copper litz, now available at electro acousti in aliexpress.
straight mmcx/2pins plugs, quite better quality jack, splitter, chin slider than any other in my stock (except cable 190).
28awg 8 cores, resistance per signal of the cable will be around 130mOhms (~25awg). superb.
couldn't resist it.. ordered one. cable
171. i'll add measurements and build & sound impressions when it arrives.
170,
171. tw cryo 7n upocc copper litz (copper,eagle,M)
171. 8 cores version:
170. 4 cores version: 252..254..268..290..[21.46g]
outer diameter: 4.3mm. total length:125cm (42cm from splitter).
structure: 0.07-0.08mm*19(OD:1.08mm/~28AWG)*4c taiwan frozen 7n up-occ copper litz (independent shield/enamel of every thread in each core); "frozen and strengthened by American cryo parts".
eagle true rhodium plated jack, sandal wood divider and wood chin slider; superb quality plugs, there is a big difference between these components (jack, divider, slider), and those used in any other chi-cable from my list; the jack costs over $12, while others jack cost is $2-3.
strain relief is stiff (heat-shrink rigid tube); this could be improved.
mmcx and 2pins terminations, 2.5, 3.5, 4.4mm jacks, available.
not very flexible wire, guess it's due to the sleeve. some microphonics, then.
sound is very clean, reference. dark background, deeper soundstage; definition is so great, that i feel better separation and imaging than the rest.
litz shielding can give even darker background than wire used in cable 165 (no litz); this is confirmed after first listening, but difference is subtle (as usual with cables).
my wish of an 8 cores version cable of this wire has been granted!
