emm cdsa SE vs. Esoteric x-03 SE or x-05

Hi all

Did anyone hear the EMM cdsa SE head to head with one of the Esoterics ? Is it worth the xtra dollars in the used market ?
I only heard the older Esoterics (DV-50 I think) but my EMM CDSA SE is much more resolving, even in stock form. I had mine upgraded with the X-upgrade that you can do later if you get the EMM which makes it superb, warm & resolving at the same time, even on redbook, and brilliant on SACD.
I never did hear the new Esoterics, so I can't comment on them, sorry.
