I don't think any modern, mid to highend converter has ever been demonstrated to be a "big improvement" over any other. There are differences and some people have strong preferences, but if you look at the results of any comparison where people tested blind you find that these differences are all quite subtle. In fact, for many they often cant hear any difference. converter differences is one the most overly hyped topics here on GS.
I have never heard the UCX, but i own a UFX which i believe has the same converters. They are excellent and for me the high cost required to get a 1% improvement is not worth it. But of course YMMV . I would suggest you borrow or rent a converter first (or buy from a place with a good return policy) and then compare mixes (blind!) made using each unit.
Another consideration is that if you decide you want to get higher end converters and are going to outboard gear, you may want to look at some DA options as well. In fact for the UFX at least the AD is generally considered better than the DA. So you may notice more improvement on the DA end. Something like the Lavry blue system where you can mix and match AD and DA units would be worth looking at. Used prices are reasonable and may be in your budget.
