Have you tried heavier, more complex, more technical Djent? Like Tesseract, Periphery, Animals as Leaders, Sithu, Widek etc?
I'm an avid connoisseur of difficult and abstract music-- I've got a jazz fusion/classical background--so it's almost like something is a turn off for me if it's mainstream or approaching mainstream. And I love extremely heavy metal and the combination of incredible musicianship, so I've a natural affinity for Djent.
There's also the Australian artist Plini you could check out, he's less metal and more in the jazz fusion/prog rock direction, but no less complex or lacking in musical chops. Plus, their drummer I personally knew and played with in high school. They might be touring US now.
