dCS Elgar plus vs. Delius - confused


This is pretty confusing for me...
I've been on dCS page,and it seems to me that Delius is "trickled-down" version of Elgar plus,with some added features.It seems to me that Delius can accept DSD data.Can Elgar plus do that?For instance,can they both accept cd-upsampled-to-DSD data from Verdi La Scala transport?
One more thing - do both of these DACs feature volume control in digital domain?Is it accesible both on the unit and on the remote?
Delius has adjustable output voltage ("up to 6V").What other values are there for output voltage?This is very important to me.
Has anyone heard both of these DACs?
Those who have heard both - which one would you rather own?
Please help-i am puzzled here
Thanks
