Hey Sean, actually I've had the complete opposite experience with AP Oval 9s, they added fullness and body to my system. But that was over a year ago in a system completely different from what I have now and I was upgrading from DH Labs T14 Silversonic. That may explain my differing view.
Just guessing, but the tube input stage of the Unico may help it sound a bit fuller than the MF. Plus, you can always experiment with different tubes to tune the sound to your liking.
