EMM DCC2/CDSD versus Esoteric X-01

To stoke the raging fires in the current discussions about the relative virtues of the EMM DCC2/CDSD combination,
I would welcome comments from those who had the rare opportunity of auditioning, and possibly trying out the Esoteric X-01, the CD/SACD only version of the slightly better known UX-1.
If you had the additional privilege of comparing either X-01 or UX-1 with the EMM DCC2/CDSD combination, your comments would be especially appreciated.
