I use banana plugs now for all my speaker connections, mainly for the convenience factor. I used to have bare wire connections, and that was a real pain to work with in the really small spaces behind the receiver! There are many companies making good gold plated banana plugs. I use the 'deluxe' ones made by RCA and sold in Home Depot stores for about $6-$7 a pair.
