NO, I have not started doubting my ears yet.
I think the best way to 'listen' is to not 'listen' specifically for anything, give it at least two weeks and then switch back, keep the conscious mind out of it, the instruments themselves will show weaknesses etc. things like tonal balance and soundstage will become apparent relatively quickly. Things like inner detail may take a bit longer to identify.
IMO YMMV of course...
