Audiophile here - if they were using a proper master, minimally a true lossless file I don’t really see the problem. On the other hand, it seems to me like I meet more people who are just into buying new gear rather than enjoying the music, which is what the hobby is to me. Don’t even get me started on snake oil like cables.
Depends on the signal level and the impedance. For speaker cables, all you need is a big enough gauge to carry the current. But for low level signals, especially less than line level (magnetic phono cartridges, microphones, guitar pickups) a good quality cable with proper impedance and low capacitance can make a big difference. If you look at professional studio and broadcast supply catalogs, you will see mic cables…
Idk what the cheap guitar cable was but any decent guitar cable will be indistinguishable from an expensive ass cable sonically. This doesn’t take into account better quality of construction and better connectors etc.
