In my experience it seems getting a truly accurate tonality and decay of a simple piano is one of the most if not the most difficult instrument to reproduce. Assuming you would agree.....why is this? I am mainly an IEM user but I find this to almost always be the case. There is often scratchiness or mild distortion when striking the notes.
I suppose this could also be due to the instrument being mic'd improperly or the recording but, like I say....it seems overly prevalent with slow piano music.
Is it my imagination?
