@williewonka Thank you for your response. Looks like you have pretty deep experience with DIYing cables. I agree with you regarding UPOCC cables & hence even I use UPOCC copper cable for speaker cable.
I would like to know how & from where did you manage to procure UPOCC Copper or silver cables for your exoeriments? I find it very difficult, some times even next to impossible to procure cables that I want. Recently I wanted to procure flat foil UPOCC Copper or Silver...I was not able to find anyone who could provide me what I wanted. Hence any help on procuring cables or conductors is much appreciated.
Regarding the point that you mentioned about finding UPOCC better sounding than rest of the conducors (ignoring the geometry & talking purely from conductor perspective). Thats quite understandable as UPOCC has very less amount of crystal copared to OFC version or even standard metal version. But UPOCC is the patented method so finding it easily and economically is going to be a challenge.
Amorphous metal (or alloys) are actually a step ahead. They are made using a method called as Melt Spinning (there are other methods as well) wherein the molten alloy is cooled very rapidly so that atoms don't have any time to form any crystal structure. Hence these are also called as metal glasses. Now since they don't have any crystal structure at all and they are very tightly placed without any (or minimal) interatomic space compared regular crystalised metal, it's going to be even better than UPOCC because of the said reasons. Hence I am looking for amorphous Copper or silver. Let me know if you know any manufacturer who can provide me what I am looking for.
