Generally speaking, I've heard some people say they felt the Zoethecus products added a bit of smearing or warmth, whereas the Neuance Shelves seem to have the opposite effect.
I have a Zoethecus z.Block 2 with a z.Slab for my amp and a Neuance Shelf under my transport. When I installed the Neuance some years ago, I did experience an expansion of the soundstage and some extra transparency. I wasn't aware of a change with the Zoethecus though. It doesn't mean there wasn't a difference, I just didn't test for one or perceive it.
I think for what you're trying to achieve, the Neuance might be the better path.
