If you've got a Squeezebox then you've probably got an amplifer to go with it. Having to get up and turn the amp on and off when you need it is just far too tedious (especially if your Squeezebox is hidden away in a cupboard or something), so we need a gadget that can turn the amp on when the Squeezebox turns off, and turns the amp off again when it turns off. Sounds pretty simple, right?
