@hakuzen this is probably a stupid question, but it's this link the current version of the vapcell you use? It looks like bundle 2 is the basic setup I'd need to stay getting better measurements...

Thanks.

Re meassuring 179 borrowing aligator clip
160...180...170...170...

I believe this one will be more proper...
yea, these sound better

my yr1030 is the old clear version.
the one from your link is yr1030+. yes, bundle 2 is what you need (kelvin clamps, plus leads)
for a bit more, you can get new yr1035, with even better resolution, and 4 pins connection instead of usb

Borrowing better aligator clamp, with lower resistance 100mOhm.

The following is the measurement :
15728747461187920721945382383616.jpg

DD 2.5TRRS to 3.5TRS
40...30...50...50...

DD 2.5TRRS to 4.4 TRRS
60...40...50...60...

Dunu 2.5TRRS to 3.5TRS
20...10...20...20...

OKCS 2.5TRRS to 4.4 TRRS
20...10...20...10...

Final Result, My conclusion for my own Measurement, DD adapter is almost double the resistance then Dunu or OKCS adapter.

Stiff & microphonic... ONLY OFC Pure Copper... and Quite pricey...

But the sound it creates... OMG, it solved some of the sound sig I need... Much better then 179...

The Highlight, all corrections in freq, & can reduce the Hiss (quite enough).

done. thank you, nice photos!
Bro....

can you tell me the very best sub-30$ we can find at ALI SALE right now?? With lower impendance.

i try to check all your cables info list but it make me confuse....

im not a big fan of only copper...

Would be appreciate if you share some great spc (or mixed) cable with lowest impendance possible.

Thanks in advance bro.

you can find them in part 3 (it will be part 4 soon) of comments, pics, and links, or in cables below $30 part 1.
lowest impedance is cable 065, but i'd prefer cables 051 or 053 (silver color).
edit:
this cable also gives you good bass and brighter treble:
https://www.aliexpress.com/item/4000009633191.html (6n occ spc + copper)
(cable 196 in my list of measurements, i'll add comments, pics, and links soon)
but spc wire has got higher impedance.

added cable 183 to the database. it's an alternative to cable 175, if you want a less bright cable than 174.

182, 183. eac AuPlatAg+AgAu 4c/8c (gold+silver,eagle,MV)
taiwan neotech oem 24k gold plated up-occ silver + up-occ pure silver99% + Au1% alloy. 28awg/core, PE sheath, from electro acousti.
structure:
AuAg: 0.10mm*10(ID:0.36mm/OD:1.4mm/28.15awg). gold plated Ag: 0.15mm?*7 (~26awg).
the result is 27AWG (24AWG in 8 cores version).
eagle true rhodium plated plug (over gold plating); superb quality plug, there is a big difference between these components (jack, divider, slider), and those used in any other chi-cable from my list; the plug costs over $14, while others cost $2-3. good strain reliefs.
mmcx, 2pins, QDC, and other terminations, together with 2.5, 3.5, 4.4mm plugs, available. you can also ask for other terminations, like 2.5mm or 3.5mm plugs for headphones, and not ear molded guides (search for desired plugs in their stock).
flexible wire, but not the most flexible; it's supple, considering its thickness.
some microphonics, then, although i don't notice them when music is playing.
like the other up-occ wires, sound is very clean, reference. darker background, deeper soundstage, which helps to better separation and imaging perception. this also leads to better definition and detail.
compared to cables 173/174 (only AgAu wire), the gold plated silver wire helps to get less bright result. quality of upper mids and highs is the same, but you get bolder bass and low mids, and some more sub-bass rumble.
compared to 175, i think i prefer up-occ copper bass than this gold plated silver bass. but i have to do further AB between both cables to confirm it.

wires used:

added cable 210 (nicehck 6n up-occ silver & copper alloy, 4 cores) to the database.
resistance is very high, but the sound you get is great, specially the bass, imo.

210. hck 6n upocc ag&cu lz 4c (light copper,M): 382..409..386..403 mΩ..[21.4g]..78..73 pF..[129cm]
outer diameter: 5.5mm. length from splitter: 40cm.
nicehck oalloy 6n up-occ silver & copper alloy litz. PE sheath.
structure: 0.06mm*22*2(26AWG)*4c. advertised as 25awg conductor.
geometry is two groups of 22 twisted strands, both twisted.
it comes into a nicehck flat zip case (one of my fav cases).
the plugs are nice looking. i like the bevel in the 2.5mm plug.
the wire is soft and medium-low flexibility.
as you can see, resistance measurements don't match 25 nor 26awg. it's around 29 or 30awg. the discrepancy could be originated by an improper litz remove before soldering. found similar issue in cable 192.
despite of the resistance, you can notice the sound stage and black background of up-occ wires here.
the sound you get with this cable is really good. i'm amazed by the bass: it's very detailed (great texture) but it has big presence and sub-bass rumble. i think it's my favorite bass from all up-occ wires i've tried.
sound is balanced, not dark, not bright. about treble, you don't get same detail and clarity than with AgAu wire (cables 173/174, 175, 182/183), but it's there.

and i have no time to add cable 198 now (new electro acousti 7n frozen single crystal copper litz cable). will do it later.
measurements have been added to the list (4 cores version).
i can advance it is the darkest cable i got from electro acousti. huge bass.

198. eac 7n scc frz lz (copper,eagle,MV)
frozen 7n single crystal copper litz. PE sheath.
structure: 0.06mm*7*7(.139s/.42mm/25.7AWG) per core; 22.7AWG (~90mΩ!) per signal, if 8 cores.
geometry is shown in the pic below. in this case, litz looks properly removed before soldering.
eagle true rhodium plated plug (over gold plating); superb quality plug, there is a big difference between these components (jack, divider, slider), and those used in any other chi-cable from my list; the plug costs over $14, while others cost $2-3. good strain reliefs.
mmcx, 2pins, QDC, and other terminations, together with 2.5, 3.5, 4.4mm plugs, available. you can also ask for other terminations, like 2.5mm or 3.5mm plugs for headphones, and not ear molded guides (search for desired plugs in their stock).
flexible wire, at least the 4 cores version. more flexible than up-occ cables.
my first try in this cable (not burn-in) shows huge bass. lot of rumble. this makes the cable the darkest from the electro acousti cables i've tried. there is good detail in mids and treble, but due to bass presence, the overall result is warm.
i'm in love with up-occ wires, because of their deep sound stage and black background, and tight and detailed bass (personal preference): this wire doesn't reach the high mark up-occ has set, although it is close.
i'd recommend this cable for bassheads, or for trying to get a darker sound from your excessively bright source+phones combo.
i'll update my impressions when i spend more time with this cable.
