I didn't say it in my post but I also meant the differences are very small. I'm also the type of listener who sits in the dark with my eyes closed listening very sharply. On those two discs my ears are telling me the SACD sounds marginally better. Is it worth it to repurchase the same cd twice? NO. But if I had a choice between a redbook cd and 2 channel SACD I'd take the SACD almost any day of the week (see: MJ's Thriller).
