I thought we were strictly talking about the “silver plated” copper cables. A $5-$20 isn’t going to be pure silver.

Quick test for presence of silver is dip it in sulfuric acid. if it doesn't immediately turn jet black, it isn't silver.

That test works as well.

We always use nitric acid, because it’s used for testing other precious metals (and ruling out the junk).

Silver = creamy white.

We always used sulfuric since silver reacts to both hydrogen and sulfur and the color change is very abrupt and easy to see.

On the topic of silver. I have 2 of the same silver cables from the same vendor. My older one is an mmcx cable, has a dull sheen to it. It is not shiny but the color actually looks like silver. The other a 2 pin version of the same exact cable is shiny. Way too shiny. I am very suspicous of the 2 pin one. Even though they are from the same vendor. The previous duller looking one I have no doubts it has silver in it since it is oxidising. Sounds great with all the phones I attached it to. This new one I got has no signs of oxidation. Again they are too shiny and looks like it is made of a different material. The way they are made look identical however. I can see them doing the old swap a roo. I have other SPC cables that have the same shiny surface.

Very suspicious. Might have to stick with copper stuff. Lol.

It is odd. I have some silver plated cables that are bright and shiny, others that are dull and obviously tarnished and still others that are turning green from the copper oxidizing. No real rhyme or reason to why any of them do any certain thing.

Any links for cables 3.5mm to 3.5mm for headphones ?

Or 3.5mm to 2.5mm/2.5mm for my HiFiMan HE4XX ?

I am looking for something like this, but less pricey:

a head-fier, @Lurk650 , is selling one now: https://www.head-fi.org/threads/hifiman-400i-balanced-cable-2-5-trrs.891996/
it look likes nylon outer sleeve instead of the paracord of your link.
and it's 2.5mm balanced jack, but not a problem as you can use one of this: https://www.aliexpress.com/item/OKC...le-Jack-Audio-Stereo-Adapter/32865122372.html
(i only buy 2.5mm jack cables now; you can use them at 2.5mm common balanced outputs, but also at single end with the adapter; more versatile).
you can ask for materials to him. guess they are SPC, but don't know more details (quality of the material, diameter and number of strands per core..).

i bookmarked these from lunashops. they look good enough to me.
http://www.lunashops.com/goods.php?id=6021
http://www.lunashops.com/goods.php?id=6134 (wire: http://www.lunashops.com/goods.php?id=5671 ; equivalent to 26awg per signal, if they use 2 spc cores + 2 copper cores)

anyway, i don't find very expensive the one you linked to.
equivalent to 28awg (acrolink 6N spc version), or 25awg(copper core)/32awg(spc core) in van damme starquad version.

This is a new cable from LZ. Crystal Copper 8 core. Sold at $59 on NiceHCK site. https://www.aliexpress.com/store/pr...l?spm=2114.12010611.8148356.26.24dc581dZM7o4e

got the first one, 2.5mm 2pin version. its conductivity has not impressed me, neither build quality.
measured L+:240 R+:240 L-:240 R-;300 DC resistance.

 

[Dsnuts]

I had the brown 8 core one myself. I liked it with a few iems but I didn't see it as being worth the $55 or so I spent on it. The ones I posted are new to the market as I just saw them for the first time maybe these newer ones are better.

 

[-rowan-]

if i were you, i'd aim to the 7N OCC (pure copper) 4 thick cores cable, sold by many ali shops, instead of any mixed copper/silver.
wire used: 0.1mm*63(equivalent to 20awg) (OD:1.5mm) *4 cores.
it's superb. measures 57(L+), 59(R+), 53(L-), 64(R-) mΩ DC resistance. very difficult to beat that, it indicates the quality of wire, plugs, and solders.

Is this the one you're talking about?

Also, do you know of a seller that has them with 2-pin connectors? The bulk of the ones I've seen are MMCX.

yep. they both are. not so flexible than others, but conductivity is amazing.
other sellers stock it; for example:

[superuser1]

Guys can you please suggest a pure copper cable either mmcx or 2 pin but not very expensive. Thanks

from my stock, cheapest one, great conductivity:


superb built quality (repairable plugs, strain reliefs..), very nice looking, good conductivity, a bit more expensive; various sellers:


the cable i posted above several times is more expensive, but you can find it cheaper at 11.11 if you make a search of "pure copper alloy" at ali.
it pairs perfect with toneking t4.
