That’s only true for data connections inside a PC or streamer which has relatively short distances. You can get better results (subjectively) with Einstein–Rosen bridges when it comes to the analog audio as opposed to digital info.
The problem is that you need to sit in an equilateral triangle to your speakers but you have a single source box even with monoblock amps. Electrons can only move at the speed of light, and there is a decent, very scientifically measurable distance that they have to move from the source
through the interconnect to amp and then to the speakers. That distance is not zero. This isn’t an issue with headphones, or at least my ears aren’t good enough to hear the difference at those close distances. So there definitely is a threshold where you just cannot hear the difference.
If you just bend the cables, it’s a lot of distance for the electrons to travel. It’s just like skiing and zig zagging. The audio isn’t as precise but works well if you need a more relaxed warm sound and a cheap mod. That’s why people like to generally keep the wires straight to have the least amount distortion. I have seen hardcore audiophiles in Japan who don’t stack the source and amp or even put them side by side but instead put them back to back so that your interconnect is straight. (You do have you be careful about components that have the left and right channels aligned vertically versus horizontally of course).
The trick for sending electrons faster than light is to fold space or do what non technical people call a wormhole essentially. If you take an piece of paper and imagine an object going from the top of the page to the bottom, there is s long distance to travel. Now imagine folding the paper in half and then stabbing a pen through the folds. You have traveled a very long distance from the perspective of space (the paper), but from the perspective of the listener (the pen), it’s quick. This is exactly what happens with audio signals that should be beyond the threshold of hearing but can actually contribute to the music.
This picture is good representation. Do you want your audio taking the long route on the left or traveling across the bridge for the most micro and macro dynamics, precision and transparency?
The thing is that the super tweeters need cables with folded space, the mid range generally benefits from a straight or S curve to give you a more forward vs laid back presentation and the bass needs extra rigid speaker cable in order to prevent any of the microphonics or back EMF for distorting the bass.
When Amir runs his tests with the APx555 he isn’t thinking about the cables like this. You can actually use old lamp cord or radio shack cable and rely on the topology to give you the desired sound to match your gear but combining the proper topology with premium cables, is aural heaven. I would liken the sound to eating a freshly picked strawberry with organic vanilla ice cream that is freshly churned but then put in a cold freezer. Smooth yet crisp and almost at the threshold of being brittle.
I am just a hobbyist but if anyone really wants, I can make a custom IconiBlast c^4 cable for you which relies on folding space to give you audio speeds that would be like taking regular cables, squaring their performance and the squaring it again! It’s pretty pricey at 1 bitcoin/ft but I will give you a money back guarantee. It’s actually a good deal right now since BTC is cheap. PM if interested.
Oh, if you are skeptical, just look at the measurements of the Topping LA90 or Benchmark AHB2 or a DAC like the Mola Mola. Those implement this type of technology and you can see they have been measured here and clearly measure well. They won’t admit they use this technology just because it’s sort of a trade secret. The problem is that once you connect speakers to the gear, you lose the transparency. There is the problem of making a microphone cable with this technology though. Which makes is tricky to measure the effect directly. Just trust your ears and look at the golfing panther you see for the gear I mentioned.
