Sounds like it might work. I have the XA777ES with the superclock 3 upgrade - Sony's DAC is very good - a bit analytical but very good - I think most people that don't like Sony's sound are looking for Euphonic stuff instead of "just the facts". I think the MF tri-vista DAC will be more musical. haven't heard that combo personally -I think you are on the right track.
I go back and forth with my Cary 308T and the Sony's DAC. The Sony's is in another league analytically, but the Cary is in a different league musically (with Mullard tubes).
