The Magic CD from Reynold is the only CD that I know of which is designed specifically for speaker break-in. The first track goes very low so you need to adjust the volume carefully while watching the woofers move in and out. This is the only CD I use for speaker break-in. I also own the Ayre, Purist, and another that I can't remember the name. Email me if you are unable to find the Reynold CD and I'll try to help you out.
