Cabling Question -Only One Prong of Spade is Contacting Terminal.

I recently got new speakers, the opening on the spades on my speaker wire is too small to fit over the post on the terminal.  I can fit one prong of the spade through the hole in the middle of the post, but the second prong sits off to the side.  Tho contact is solid and is secure, but only about one-third of the spade is in contact with the speaker terminal. Will this affect sound quality?  there any reason to change out the spades to something larger or switch to banana plugs?
