The demosaic engine in ASP leaves a result that can't be sharpened, by any means. Any kind of fine diagonal goes jagged and appears 'weak' if not sharpened.
This is a major deal for me as I love the rendering and usability and ASP, but for the common task of sharpening eyelashes in portraits, well, it just doesn't work. I have to go over to Lightroom to develop the raws and then they are as flawless as the jpegs that Olympus cameras produce by default. And Lightroom files can then be sharpened.
This is not a 'you won't see it unless you print huge' issue either. The weakness of fine details is visible in even 8 by 10, which is the smallest I print. Go larger and you won't go larger, because it looks fuzzy. Same size print in Lightroom (or even Rawtherapee) is tack sharp.
Maybe a 'high quality demosaic' option, could be added, if there would be a performance penalty with a better algorithm?
Other than that, ASP is truly superb. Please please fix it.

Best of luck with this - some of us have been complaining about the Bibble (now ASP) demosaicing algorithm for years to no useful effect whatsoever.
