I have an older audio system and the plugs that came with the system are the normal silver plugs. I heard over time the silver plugs loose performance and so I want to upgrade to a gold plated plug. I am wondering to get the sound quality back to where it is suppose to be, do I have to cut off the old plug and connect another or will something like this do just as well? http://www.radioshack.com/product.as...5Fid=274%2D915

Thank you very much for the help
