Cables are luxury and convenience.
Mega priced ones beautifully designed for looks, but experimenting with sound differences is truly sufficient few bucks instead of $30,000. All I did when I was child is to connect solid core wire or stranded picked up from the electronic lab where I was learning. I wasn't sure how much it was worth(perhaps half-dollar per meter), but I heard differences especially if solid core wire was used.
I can bet lots to find same wire that will sound same or better than $30,000 cable.
They made only for ones that don't know the difference between $3 and $30,000. Many would agree
