I am looking for commercial sfz libraries. This means intended and sold as sfz, not converted, not user- or script-generated sfz mappings.
The bigger the better.
More expensive, the better.
Needs proprietary sfz-extensions/engine? Also fine.

This is not for personal use but for Linux Audio research.

Do you know any?

Garritan immediatly comes to mind : http://www.garritan.com/products/personal-orchestra-4/
It seems to be sfz libraries as they are referring to aria engine which is about sfz : http://ariaengine.com/
By linux audio research you mean testing a new sfz player ?
