Anyone have experience with using de-esser for sibilance in home audio system?

Pretty much all vocals. Used to be just female soprano vocals but it's no longer gender-specific. This is one reason I suspect my ears. 

I looked at de-essers on Sweetwater. Some are fully encased and mounted horizontally; others have only front plate and mounted vertically. 

Not interested in software. 

A de-esser is a frequency tuned compressor.  I would start would the EQ first. Try a parametric and gently scoop out the frequencies that offend.  That could be all you need.  Adding the compressor part can be tricky in that many popular compressors have a distinct sound.

Never heard of that as an ear issue. Same distortion in the car? Sure it's sibilance and not resonance?

Thanks for the clarification.

Can you recommend an EQ? 

I've read 5 - 8 KHz is correct range but others say 3 - 10 KHz.  

Um, first, does this happen with headphones??
