$1300-1500 DAC

I’m thinking of adding an external DAC to my secondary system. I’m running a bluesound node 2i, RCA out to a Schiit freya+, RCA out to an Accuphase P-250 (beautifully restored) amp, to a pair of ascend acoustics Sierra 2ex. It already sounds awesome, but y’all know how this is... I want more. 

Im looking at a Schiit Gungnir Multibit... the price is right and it’s well reviewed. 

I will say that, in my main system I use a Simaudio Moon 280d and it’s awesome. 

Any thoughts? What else should I be looking at?
