Can sibilance be eliminated?

Yes. I would start with power conditioning and resonance control. There is a wealth of info in the thread archives. Digital playback does not have to be annoying.

I have a CD only system & it has great detail that exhibits no sibilance but I wouldn't necessarily say that was a condition relegated to digital payback. Your system synergy (or lack of) will have a lot to do in determining what is the best direction to go regarding your particular problem.

Since you did not list any of your components, it's difficult to even begin to offer suggestions, as it could be any number of things.

I would start with microphones and the rest of recording equipment first.
