Sony HAP-Z1ES vs. Cocktail Audio X50

Looking at either the Sony HAP-Z1ES or the Cocktail Audio X50.  Using the Anthem STR Pre-Amp so do not necessarily need a built-in DAC.  My amplifier is the Anthem STR amplifier and I have a pair of Paradigm Persona 9h speakers.

Would be interested in feedback from anyone that has experience with the Sony and/or Cocktail Audio devices.   Thanks!
