Thanks for the initial impressions and looking forward to your review!
Definitely more close to the CKS70. What I'm finding is perhaps a little less sub-bass. One thing is though, that the 90Pro is much, much faster than the CKS70, even in terms of bass - so that you might not get that swelling bass sound from them. They tend to be more accurate, but you might not get the same warmth from cellos that the 70 do... however, that said, bass impact easily outstrips the RE0. This is unamped.
However, I just did an experiment, listening to the 90Pro out of the headphone amp on an Onkyo receiver, hooked up to a PS3 with the 176kHz upscaling (Bitmapping mode 3). Amping completely, completely changes the sound signature! It removes the muffled tone completely, instrument separation improves. Comparing them to the same setup with the RE0, I would say, the RE0 still has better high extension and more forward mids, but the detail in the mids on the 90Pro and soundstage/imaging are better and the 90Pro is overall smoother and less fatiguing. Bass tightens up significantly when amped, but because the overall sound signature becomes much more balanced, it almost seems like there is less bass. Overall sounds pretty incredible, so this must be what people mean when they say portable sources don't drive BAs well.
I feel like I'll say too much and have nothing to say for the review lol, but the amping discovery was too cool to keep quiet about.
