I think many of us (including myself) have/had a strong bias to assume more expensive cabling should sound better is some way - but that’s a very weak correlation, if at all.
100%. One example of this is companies that sell direct and skip the distributor AND the dealer mark ups.
Q: What is the best cable?
A: The one with the best margin.
Kidding...sort of...
I also hate the marketing fluffy, BS terminology. Just describe materials, construction.
Anyway, I agree cables matter but I either buy direct or used and don't believe you must have a complete loom (although they look nice) because the applications/requirements/synergies are different between SC/PC/IC etc.
I.E., the speakers have no idea and don't care what ICs you are using.
