One area where my experience with the mhdt DACs differs a bit from the reviewers is that I believe the COnstantine to have better high and low end frequency extension and better dynamics overall than the Paradisea. The Constantine's bass may come across as leaner overall though but is spot on in my main rig.
Tube rolling does make a very significant difference though with the Paradisea and I have only tried two different tubes to-date.
Also I find the Constantine is dead quiet.
I have some background hiss with the Paradisea, but you have to put your ear right up to the speaker with the volume well up to be able to even hear it, no worse certainly that what you would expect from most decent if not the absolute best phono rigs.
