I'm certainly not in your league as far as price but maybe my opinion will help.
I have a Delos and I certainly think you can't go wrong with the Kleos. The Delos does sound a bit like Dynavector to me but more detailed with more bass. The Kleos should be even more refined.
I have a Grado Statement Platinum that was retipped by Soundsmith with the top stylus there. I bet it is very similar to the Reference. Very fast and warm at the same time. Very nice for what I paid. Probably not going to have he top notch imaging and depth the XV-1S has.
