A cable is Neutral if it's not in Drive or Reverse

Thank You! I was tempted. Electrons have no memory of where they have been. Barring impedance issues when using an analog interconnect and digital to some extent, no cable should have a sound at all. Of course the level of disability and remoteness of the person building the cable, the better it will sound as if by magic. If built by a blind person on a tiny island in the South Pacific, the sound will bring tears to your eyes. if that person dies, the sound will immediately be twice as good and you will explode with passion.
On a serious note, there are some areas where material DOES matter, keeping electrolytics out of the audio path in circuits and crossovers is the biggest one, speaker cable of sufficient gauge so as to give the amplifier better control of the speaker is another. If the output impedance of a component is higher than the input of what it is feeding, you will get an unnatural roll off at the high end of the range. I can think of so many design considerations that will give equipment better or worse sound to the point that the interconnects are so far down the scale it's not even on the chart. If I didn't like the sound of my amp, the first thing I would look at is which op amp is used on the input and go from there, I would not suspect cables unless they are so poor that even a coat hanger is better.
