Here's a good tweak I put under all my components, speakers and my Clever Little Clocks too. I took three pennies and stacked them on top of each other and then wrap them in tape and put them under each component feet (I have mine on top of each Mi-Roller) I use three under each component. Try this and see what you think after a few days.
