I finally got myself a bottle after forcing the SA to get them out of their loading dock downstairs. LOL!
I think the sillage is about the same, the only difference is that the EdT SEEMS more noticeable because it captures the brighter aspects of TdH. The parfum smells defintely more compact and dense.
I used to describe the EdT as oranges sitting in a cedar bowl in the desert. The parfum means business. After a short introduction of citrus notes, it deepens quickly to smoky cedar, a bit of lavender, amber, and patchouli. It definitely doesn't smell as complex as the EdT, which has impeccable nuances of JCE's artistry using its transparency to show off its natural complexity. I think other Noses are envious of his style! The parfum might be a letdown for many because it doesn't smell as complex. Not as practical as the EdT, but is no doubt sophisticated and modern. I would definitely call this a smoky woody-leather scent.
This convention of "parfum" is not the same as the classic sense. It's not all about concentration and longevity. Same goes for their Parfum de Merveilles. You spray like an EdP and dabbing wouldn't do you any good with this one. I think JCE is trying to interpret a certain focus of the fragrance, in this case the woodsy depths of the fragrance, and christening it as Parfum. I wouldn't be surprised if another flanker will be created focusing on the more citrus aspects of it, or goes oriental with it by adding vanilla or gourmand notes.
