If your budget is $10K, why not buy a used KX-R. You should be able to get one for $12K or less.
If you go with a CJ Art II, the ACT2, or the CT-5, I am sure you will not miss the KX-R terribly. Or you can get the Audio Research REF3, LS26 if balanced is your thing. All of these are super sounding zero negative feedback designs.
However, the tricky thing for me with any of the above options is that all of these preamps have too much gain for my situation. That should not be an issue for most.
