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 (...to me).  There's also definitely more low end.  Very bassy.  The D70 didn't have this low end.
