There is something I would really like to know if others experienced it. I am not a believer of that snake oil **** that some hifi dealers sell. SO I wanted to have nice looking speaker cables and I bought the cheapest 2,5mm² OFC cable I could find on Amazon. I peeled 2 (+)&(-) poles of the cables so I would have four cables per channel 2x(+) and 2x(-). With this configuration, I have created three stereo sets of cables - as mentioned, just for the looks.
1. I have twisted a pair of 2 cables clockwise and then twisted those together counterclockwise.
2. I have twisted a pair of 2 cables clockwise and then twisted those together also clockwise.
3. I have braided/woven 4 strands of cable and tried to make it as accurate as possible for the looks.
They all had the same initial length.
So cable 1&2 didn't sound any different than a straight cable. But cable 3 sounded remarkably bad (I lay out the window and say everyone would discern those in blind test.) I still don't know exactly why this was or which physical effect has caused this, but that was when I started looking into cable geometry... For now, I just use straight cheap OFC Copper Amazon wire with some nice looks
