Laid back DAC under $800?

I've always been pretty sensitive to highs (it sucks).  Just got a Topping D70 and really like it but it's hard to listen to for long at decent volume.  Any recommendations under $800?

Thanks all!
Just got the Codex set up.  So far, pretty happy.  Still detailed but not quite as bright and clinical ( me).  There's also definitely more low end.  Very bassy.  The D70 didn't have this low end.  
FYI Metrum went out of business so if you go that route good luck on support if the DAC malfunctions
