topping d10s je la, or if budget allow get topping e30.
but honestly you dont need to spend tons of crap for dac because even mobile class ess sabre/akm chip already very good, expensive dac just provide you extra feature like bluetooth receiver or XLR/balanced output.

personally i rather spend on amp that colors the sound (not something with negative feedback of course), distortion-fest audio-gd is still my favorite on this
