The Dusk blows it out of the water. Everything about the Dusk is just "cleaner" sounding and more refined. It's not like I can't pick out what's going on on the Hexa, but the Dusk makes it easier. Imaging is good as well. I use it for gaming and have no real issues placing things where they are. Haven't really used the Hexa for gaming much yet

Edit: I've used the Hexa a bit and fuck me the tuning is so good to me. I've learned I like hearing every micro detail over a thumpy bass. I don't look at my Dusk the same way. This is more a personal discovery I think then anything but I love these fucking things
