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!

It varies but the area that most people find tiring is around 4.5khz you might try putting a slight notch there say -1db. Leave the rest alone and try it for a while if it's  a little better but still to much try -1.5 in that same area. Don’t increase anything without adjusting headroom down a few dB.
