I just used the old method of playing music and waiting for it to burn in. It's not like you are going to be contaminated or anything. So, you have to wait awhile. Big deal. I just kept track of how many hours of CD I played, and how many hours of SACD. When you do it this way, you actually hear the stages of break-in. And it usually happens in "blocks". You will suddenly notice something different, after awhile. Then it will stay about the same for awhile, and then bang, another difference. At least that is what seems to happen in mine. I think it is a good idea to learn what break-in stages sound like, for your own knowledge. If you always use high-speed break-in methods, or non-listening break-in, you will never know what intermediate stages sound like. This information can be helpful when auditioning equipment.
