I think that several of us have tested it and hear it, this is enough for me to believe that it's there. I doubt yours, mine or another persons came from the same batch, I'd be more apt to believe we tested from different batches, but this is only an assumption. As you say, I don't think this is worth the effort. My player is far enough from my ear that I over look this issue and it doesn't introduce any noise into the music.
