Hahn specify perceptual rendering intent with BPC off for their canned profiles.
Try that in your softproof, see if it changes things. I get lots of difference with these profiles when I change from relative to perceptual.
Also, as someone else suggested, VFA setting seems to lay down too much ink. Either play with the ink adjustement or try to use Archival/Enhanced Matte or Ultra Smooth Fine Art paper settings.
But first check the rendering intent.
Also make sure you download the latest profles from the Hahn site.
