Sony sacd es777

Has anyone tried outboard dac with this player that improved already good sound.This player IHMO would make an excellent transport.
You will find a good deal of comment on just this subject on perform a search; Les Lammers is one of many that have done so and finds the result positive. I have used an outboard DAC with my SA-14 and it would be hard to go back. Jim.
i'm using the dodson da 217 mark 2 with the sony,its a great combination for normal cd's & you stll have the sacd thing covered
