1/4 Inch Spade to 5/16 Inch Spade


My speaker cables have 1/4 inch spades which are cold welded on. My McIntosh terminals take 5/16 spades. Is there a 5/16 spade that will take a 1/4 inch spade on the other end? What I am essentially looking for is a 5/16 spade on one end, and a screw terminal on the other end to take the 1/4 inch spade. Such a thing exist and if so, where can it be purchased?
