Jayarr,
Seems to me the best way to find out whether or not what is going on is brain acclimatization or equipment break-in is to buy a new unit and play extensively for the first day taking notes in the process. Play continuously at low volume for 2 weeks without listening.After 2 weeks, now listen and compare notes. I know, aural memory is notorious fickle but at least this is a relatively easy way to try to examine this phenomenon.
