Jay's DAC 2 SE vs. Jay's DAC 2-MK3

I've been fortunate enough to borrow a Jay's DAC 2 SE to compare to my present DAC, a Schiit Bifrost 2/64.

I'm curious if anyone has compared the two Jay's DAC models mentioned in my title and if so, what differences you found. The two DAC's certainly look very different inside.
