Charles, when I got my EP500 a little over two years ago my instinct(as always)was not to pay a dollar more than was necessary for a cable that would do the job of connecting it. So I ordered this cable from MonoPrice which was about $4 at that time(couldn't wait for the price to come down). I can confirm that the connectors are snug but not too snug and that in all other ways the simple job of hooking up a sub is done flawlessly.
