Many audiophiles fall victim to snake oil cables...forgetting or simply not acknowledging why cables are different/may sound different.
Metallurgy - silver is the best conductor of electricity. High purity copper with lots of .999s is fine too. If the manufacturer doesn’t make fantastical claims about improvements; but simply markets their cabile as "high-quality" I think it’s worth buying, provided of course, the cost is not thousands of dollars. Consider if you will, how much food --> Swiss Chalet, other electronics, etc. you can buy with that money instead??
When an amplifier is driving a reactive load (speakers) in this case, how well speakers conform to the damping factor can impact frequency response. Some so-called "high-end" cables have been known to act as antennas and pick up noise; and in turn, they adversely influence how the speakers respond when fed power, thus altering the frequency response you hear. It's not clarity or anything magical - it's just that certain frequencies have now been attenuated or accentuated.
In particular, I have found thin CCAW wire (thin-sounding) to be much interior to high purity copper or silver, regardless of AWG. Lower AWG just means less losses; even if we can’t discern them in a repeatable manner. Hearing the difference after days, weeks, months, or even hours is simply the brain working harder at filtering the sound you hear, since you are paying more attention.
While speaker cables can sound different, the idea of improving sound quality just because of the cable (rather than the inherent performance metrics of your audio components + speakers is silly. Cables should not alter the sound, they should get out of the way and allow your audio gear perform at an optimal level.
