For my current system, I knew my speakers were known to be able to achieve disappearance. But after being broken in, they did not. So there was a period of six months of slowly repositioning them until they were optimal. Then suddenly they were gone. But it does vary. There are some albums... like some of the silly recordings when one musician is recorded directly in the left speaker and one in the right... dual mono... I don't know what they were thinking. Those do not disappear.
