As far as sound is concerned, hardly anything noticeable even with the most sophisticated measuring equipment, including your ears.As far as your wallet is concerned, a great reduction in its thickness.Measured in ohms, the difference in the resistance of 24-gauge, 1000-foot-long silver and copper wire is a mere 2 ohms. Your connections are likely to have more resistance since some of them are likely to be brass.And... you are very unlikely to use 24 gauge wire for a 1000 feet.Basically, NO DIFFERENCE.Others who claim otherwise need to see audiologists as usual is the case in this forum.
@cakyol It’s rather sad if you can’t hear the difference in speaker cables. IMHO either your ears and/or system is sub-par. There’s much more to cable design than gauge or resistance. Live happily in your ignorance, but your impressions fly very much in the face of almost everyone here. Either you’re right, or 95% of the rest of us here are right. I’ll leave it up to the OP to make his own decision.
