If you are asking me, the Fourte' doesn't come in a custom format yet so it was not an option. In trying it, the fit didn't need to be perfect to get the incredible sound it produced, but comparing my A18 custom fit to the U18 and Fourte, the A18 was always perfect requiring no fiddling. My ears have an extreme bend that makes getting a good seal with universals very difficult. As has been said many times on Headfi, once you go custom, you rarely come back.
However, in a perfect world, I will own both as they serve very different purposes for me. So I am hoping to see 64 Audio launch the custom Fourte' this year........gotta have something to hope for.
