We would say, yes, they make a difference.
Was using standard 16ga as speaker wire in long runs.
Years back, switched to locking plugs with 8ga wire, in short runs of about 1foot to 1.75 foot as my runs to the amps. They sit 8 inches from the speaker, . There is a definite bass increase, as well as soundstage.
Silver plate or core rca and speaker wire, did increase the top end frequencies.
