I recommend saving up a bit and getting the IM03. They're effulgent.
Of course, I haven't tried the CKR9 or IM02. Of Audio Technica, my experience is limited to the 03 and 04. Both amazing, but very different.
If you're actually looking for an upgrade, and not just something new, I would look at the IM03. Lots of bass, incredibly naturalistic vocals and timbre, and just enough treble that you don't feel you're missing anything important, while remaining safe from fatigue.
But if they are a bit too expensive, I understand. Budgets are such a drag in this hobby.
