I have a black ice also and the first 10-20 shotsI noticed it too. I went over my bow as you are doing and didnt find an answer and thought that maybe it was just me that was hearing it.I lowered the draw weight(came from the factory set at #71) to my desired weight and the buzz went away. I would see if that helps you out at all. I then put a meanV on it and nowI hear almost no sound at all.
