well i have the both the DAC-AH and Zhaolu D2.0
i'd say they're on the same level though have VERY different sound signatures, my DAC-AH - running @ 8volts, heatsinked and paper in oil cap passive outputs - is much more mellow and smooth, some like to call it the "analog" sound.
on the other hand the Zhaolu (i have the AD1852 chip, upgraded ELNA capacitors, blocking caps bypassed and with 3 x LM4562s) is very detailed, and emphasises a lot on the treble sparkle, and has a very fast bass slam, it is very involving.
each has their role in my system and i think both are fantastic value for the money.
