Back to the semi-original question, I have a Denon amp that I use to power some very old but great speakers inside and some JBL outdoor speakers for the yard. I'm not interested in putting the music on an ipod or any such personal device, I need my whole neighborhood to be able to listen with me(they do now and they love it). But seriously once all this is on a computer, how do I link up to my existing stereo or what new equipment do I need.
