Sharing my experience, In 55 years of owning audio equipment, I've never heard a mind-altering difference if you swap out one quality cable with another. I have heard differences but nothing that ever made me say, "Damn, I just have to have one of those."
I connected my current system together with Purist Audio products and a couple of other manufacturers of like level and the system sounds fine to me. The audiologist tells me I have some specific hearing losses (different in each ear) so, at this point, if there is a difference I'm probably not going to hear it. Makes it a whole lot easier than chasing the ever-changing world of the "best cable for my system."
I understand people who do it as a hobby, it's never been a hobby for me, I treat it like it's a system to use not futz with trying to find the ultimate sound for the money I have Holy Grail pursuit.
If you enjoy tweaking your system - and cables are the latest do-dad - have fun doing it. Just look out for those fuses...
