Hey @pvanosta,
Since you already have the NUC you don’t need the Bridge at all. Besides, a lot of DS users here use an extra “reclocker/converter” box that converts USB to I2S and seems to work perfectly with de PS Audio DS. About the DS vs your other “still in the running” devices: The DS uses an approach that is as refreshing as simple. While “the others” use off-the-shelf ADC chips PS Audio uses a complete different approach that sounds real surprising. Since I already owned a Totaldac stack, I don’t have a DS, but I would’ve if I didn’t had it, that’s fur shure…! Just sayin’…
For that box: Matrix X-SPDIF 2
