If you are using a cheap twin RCA cable, this one will improve your sound - seriously. It doesn't look strong though, so please don't use is for everyday plugging/unplugging. For single installation it's a beautifully designed cable with great plugs. If you are touring and use i.e final scratch system, this cable will be a great choice anyway. Just get a spare one if you can. For the money you earn from your live show you wouldn't go wrong. Just remember to gently twist the plug in the right direction during plugging or unplugging and do not pull or bend the cable. Try to get it as short as possible.
