Couple of OCC Speaker Cable Options

I make my own with OCC copper in Teflon from Partsconnexion.com and they sound great. Don’t know the ones you’ve linked to but Amazon Prime does returns...

I don't have any experience with either one but that Amazon one is the one I would try.   Certainly, given the insane pricing in the world of speaker cables, it is cheap enough to give it a try and see what you think.

I might just do that myself, and see if it is better than the 12 AWG Star Quad set up I have now.

BTW, years ago, I had a neighbor who had a very illegal CB transmitter which was also very noisy and had harmonic noise all over the spectrum.   It screwed up my stereo big time until I found a pair of 16 AWG coax cables.  That cured the problem completely.   All the other cables were coax, so I thought I would give coax speaker cables a try and it nailed the problem.   For reference, his transmit antenna was about 75 feet from my stereo. 

i personally would not trust ali express, even for purported high end copper speaker cables

they are so famous for being purveyors of made in china knock off stuff that looks the part but has been decontented in a myriad of ways...
