Low end. Cheap. Generic. Otherwise bang for buck cable thread!

Graphene is a single atomic layer of graphite.

I'm not trying to start an argument but may I ask where you found this information? The part where graphene powder or flakes are not as effective as sheets.

For starters, what is claimed as graphene powder or graphene flakes is just graphite.

Graphene is a specific state where there is a single continuous layer of carbon atoms, and only has special properties under that state. When you break it up its just regular graphite.

The link opens up on my phone, I've checked. My apologies if the link did not work universally. The paper file is attached. In my opinion, it is the main credible paper (very good scientific journal).

Yet, the real bulk measurements are to be seen
I am sure there will be many companies out there evaporating carbon on copper wires and enjoying amazing profit margin if graphene cables are purchased.

Once again, without reliable bulk measurements (not even asking about audio measurements), the benefit of "graphene wires" is about the same as the coat hanger wires - both can give "the best sound" to some ears and we can put an end to this discussion.

Did you even read that article?

3. Conclusion

In summary, we made a breakthrough on the trade-off between carrier mobility and carrier density in graphene, and realized high electron mobility and high electron density simultaneously in graphene by embedding it in metals through elaborate interface design and morphology control. As a result, an ultrahigh electrical conductivity, three orders of magnitude higher than the highest on record, is obtained in such embedded graphene. The hot-pressed graphene/metal configuration provides a novel platform to explore electron behavior in graphene, because it is fundamentally different from the previously reported systems such as suspended graphene, graphene deposited on high-quality substrates, and graphene covered with high-k dielectrics. In the corresponding graphene/Cu composites, an extremely low graphene volume fraction of only 0.008% is sufficient to yielding an electrical conductivity as high as ~117% IACS, which is significantly higher than that of Ag. Much higher electrical conductivities are expected in graphene/Cu composites with a sub-micro/nano-structure. The here presented results will open up new opportunities for graphene / copper applications, which could lead to higher efficiency and performance and less energy consumption in electrical and electronic applications.

Can you quote which part of that article indicates this, "the benefit of "graphene wires" is about the same as the coat hanger wires". Maybe you should start a petition to strip Geim and Novoselov of their Nobel Prize in Physics with your internet skills.

I think we should just end this right here.

The bold part is not the question.

Any recommendation for a light, flexible 2 pin cable ?
My reference so far is an effect audio maestro black. Really nice for 100€. But 100€ to pair with a cheap IEM is not really smart I think.

I wonder if there is something similar in the 30-40€ range on Aliexpress
Copper or silver. Don't really care
Thanks

I've got a 2 pin 8 core headed my way. I'll let you know how it is when it gets here.

We should end, definitely!

I took quite a bit of time to look through 5+ recent papers. The cited one is definitely the strongest and the good science (very good journal and respectable research, yet not to be "overstretched" and "overconcluded")

I did read the paper not just conclusions.
The measurements there are for 8- and 25- micron films performed in a scanning probe microscope (far from standard bulk procedures).
When bulk standartized measurements will be demonstrated - we can discuss it.

My first batch of cables from XINHS should arrive this week (maybe even the second batch with DHL Express) and that includes their 4-core graphene cable. I will measure it and see how it is.

CEMA has some good cables in that price range and so does XINHS

Ok... lets go.

I'll ask again since you decided to pretend I didn't ask, where is the quote from that article that indicates this, "the benefit of "graphene wires" is about the same as the coat hanger wires".

I got news for you, if you read the research paper and your conclusion is the opposite of the conclusion of the author, your nemisis is reading comprehension. I presume your "interpretation" of 5+ recent papers, of which only one you posted a link to, which actually fuels my argument won't negate 100+ research papers published by major news outlets, universities, medical journals, etc or a Nobel Prize in Physics will it?

We'll just chalk it up to the fact that english isn't your first language and it was a misunderstanding (I'm giving you an out here, you should take it).

I give you that shouting louder and pretending to be confident where you may have no clue may work sometimes, as in selling snake oil.

Coat hangers is a famous blind experiment, after which cable salespeople avoid double blind experiments as a plague.
I am not even talking about blind tests with "graphene" cables, just simple comparative measurements of bulk conductivity rather than the non-supported claims stemming from measurements in thin films with a microprobe in the paper (you did not show any documented measurements).

We are not also talking about AC measurements that can test what high-frequency distortions from multiple carbon-copper interfaces can be (many pay more for "defect-free" in cables). Graphene/copper, if at all functional, is crazy heterogeneous.

You did not answer my simple scientific question about "multilayer graphene" - that shows louder than your multiple other words.

I was curious to go through the good research papers, it was interesting; going through 5 papers, and reading one in more detail, takes time; claiming about hundreds of papers out there - takes few seconds. The onus should be on those who made the claims to show the proofs; you may not just not getting it, it is OK...
This discussion here is not much meaningfull, sorry.
So I have finished here ...caveat emperor...

P. S. Thank you, @RikudouGoku for taking on these measurements - comparing exactly with the copper cables of exactly equal thicknesscan be hard, but based on your measurements everyone can decide more informatively.

I'll edit this to end it. I'd like to see those papers, if you don't mind posting the links.

I'll just leave it at that.

Just purchased the kz zax!
Which cable should i purchase to improve a little bit the imaging and the depth of the soundstage on the kz zax over the stock cable? Budget is 20$.
On the "Knowledge Zenith (KZ) impressions thread" someone says silver wires are not recommended for kz zax so here we are some copper wire cables but i do not know if they are good foor kz zax:

faaeal cable but no qdc connector

https://www.aliexpress.com/item/4000400771561.html

tri through cable

https://www.aliexpress.com/item/1005001514590570.html
or
https://www.aliexpress.com/item/1005001515077125.html

kz upgrade cable

https://www.aliexpress.com/item/4000266255799.html

Are 8-core or 16-core cables better for the kz zax?

Thank you for help!

 

[linesman]

IE80 has a unique connector and Kbear doesn't offer that option on this cable.

Looks like this:

Thanks for replying. Any link to a cable that's similar to Faaeal 4 Core which I like for price and highly recommended here. Struggling to find anything interesting in Aliexpress.

Looks like the only thing that is being talked about is graphene cables

just kidding, the Tri Through is a safe choice
