With regard to my system I find that Shunyata cables matter. It will be a long time before it is fully loomed at the higher ends though.
Interesting video on cables
At the risk of opening up this can of worms again, my brother sent me this video. It’s incredibly interesting and goes some way to showing why cables matter and that all cables are not equal. These are USB cables but I’m sure the principle applies to speaker and IC cabling.
