Per @eclein and @Brause comments, I had added the CCA C10 to my prior ZSN order. And as @eclein says, it’s very clear these share some parts with the ZSN. Other than not being screwed together (which I don’t think is actually needed with the ZSN, see above), and a change in the style (if not the shape) of the backplate and the connector, they look essentially the same.
First impressions are that the CCA C10 take my favorite parts of the ZS7 and ZSN, remove most of the bits I didn’t like (i.e. there’s no driver flex, they’re not as energetic in the top end as the ZSN, but more so, and with better clarity than the ZS7), and then split the difference on price.
I prefer the finish on the ZSN (bright silver on the backplates rather than a flat, aluminum, finish) and the build of the ZS7, but sound wise this is, so far, the sweet spot between the two.
