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!
I found a used Ayre Codex for $900.  What do you think?
Well, I ended up getting the Codex for $800.  Hopefully, it was a good choice for me. 
NAD M51. You will not be disappointed.
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.
