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?

Thank you but I already have some Transparent adapters like that.  I was hoping to go spade to spade but it doesn't seem like anyone makes what I am looking for.

There are no audio or repair shops in my area and the speaker wires go under my floor and would need to be accessed from the basement.  Not worth the trouble to remove a pair of 22 foot cables and ship them.
Maybe one of the cable sellers (like Blue Jeans) could custom make you a jumper with 5/16 spade on one end and a screw terminal on the other?  Wouldn't be too terribly expensive, if it's possible to make it work.
Use a Dremal Tool to touch up the end that needs to be enlarged.  It doesn't take much to make the opening 1/16 inch bigger.
