I know topaz is a problematic format. I'm amazed that it can be converted in any reasonable form. However, to quote pwalker;
One thing that I've noticed is that for some books, calibre does a poor job of changing from mobi to epub. I have had some books that looked like terrible scan issues, but then when I happened to read the book on the kindle app, those scan issues disappeared.
His talk of scans certainly suggests topaz, but as I understand things topaz files have their own file extensions, and would not use mobi or azw3.
