IMO, the question is not, as you posited it, who thinks an expensive cable is "better" than a cheap cable? The question for an audiophile is, can you hear a difference between cables? If there is indeed a difference, then one of them may very well sound better to you.
I recently compared two relatively expensive cables, both at a dealer and in my room, and the difference is obvious and easily heard. One is Cerious Technologies Graphene Extreme speaker cables, and the other is Douglas Connection Alpha 12AWG OCC Speaker Cables. Now, the GE cables are composed of silver, copper, and graphene, while the Alpha 12 cables are made of Furutech FS-Alpha OCC ≒12 AWG conductors. The GE cables immediately present a wider, more open sound stage, with more highs and with more clarity and detail. The Alpha cables immediately render more bass slam and warmth.
Now, the question of which is better is entirely up to the listener. I like the slam of the Alpha cables, but the clarity, sound stage, imaging, and vocals of the GE cables is just addictive. I'm still evaluating so as to be able to soon make a choice.
