Did you try the eliminator at different strings and different locations on the afterlenght? An eliminator in the wrong place has no or a negative effect on sound.
You can try this type of eliminator:

I find this type much more effective an less dampening.
I had two eliminators on my instrument to make it free of wolfs, but since I have plain gut with Spiros I don't really need them anymore.
Previously I had G & D Oliv, A & E Spiro, and the wolfs were there, but under control. When I changed the Spiro A to an Eudoxa, the wolfs did increase extremely. Different strings can change the resonance of the instrument dramatically and alter the sound and reaction of the other strings, too. You should consider changing strings, if careful placement of a simple the eliminator doesn't help.
