At this point, it would be silly to say cables don’t sound different...They do.. I have picked out cables in my assortment 18/20, 24/25, etc times in a blindfold (statistically significant).
But, there is absolutely no guarantee that one will always pick the sound of some expensive cable over a cheap cable whilst seated in a blindfold.
Here’s an example where 2 guys picked a 27 dollar cable’s sound over some 20k+ cable in the host’s supposedly "ultra high end" system.

I am sure i can produce such results over and over if i had guys seated with a blindfold in my house.
On the same note, some of the best " sounding" cables on earth continue to exist on aliexpress at a cost anyone can afford. If you have a larger bank balance, some predictable options exist within the audioquest lineup. Even on the latter AQ line-up, passing a blindfolded test is like pulling teeth between a <1000 dollar AQ cable vs a couple of 5k+ AQ cable on one of my tweaked out rigs. I have tested myself and a couple of golden ear bats i know several times.
IME, the diminishing returns for cables can hit very early...around a 100 bucks for most guys in most rigs. Some guy like Ken Ishiwata or the Yamaha, tad sound master guys may be the exceptions to such observations (to some degree)..
