The issue of the efficacy of cables (as well as the question of cost) is not easily resolved unless one works with sets/looms of cables. Many people do not, and thus have only hearsay to discuss. :(
It costs money to conduct such comparisons, and most audiophiles despite their insistence upon being serious, are unwilling to put up the money to do so. Between the percentage of those with hearing loss and those unwilling to conduct comparisons with sets of cabling, this issue will never be resolved. :)
