One quick addendum (albeit from audio memory)
I previously noted a difference between the balanced and single ended outputs on the Vivaldi and my preference for single ended. The difference manifest as somewhat of the same sense of compression and homogenization noted in the direct so perhaps this is largely a function of how dCS have implemented the balanced output (perhaps another amplification stage).
I did not see any difference in soundstage however between the two connections when going via the amp -- so as @shadorne suggests perhaps that is an (artifact) of the pre-amp 😏
