If I, or anyone else, plays a recording of anything (LP, CD or SACD) for the first time in many months, or even years, and hears things he's never heard before, or hears as I do, an all new level of clarity and detail, then the improvement is real, and not imagined. Even my wife, who's sick and tired of me constantly asking "which sounds better" whenever I switch things around hears a difference.

If you hear something for the first time in many months, that just furthers the argument that you didn't remember what you heard. There are too many variables that could have presented themselves between the time you heard it a few months ago and when you last listened to it. The only real improvement that you heard was in your head. Digital devices will not need a burn in. The sound you hear are just 1's and 0's or like what someone else said, translates to, on or off. "Burning in" will not affect this, because like I just said, it can be either on or off (the bits), and it's the combination of these on's and off's that translates into the sound that you hear that ultimately come out of your speakers. The human mind is very powerful, as you know, and can make you "hear" things you haven't before. Especially if you "want" to hear something.
