Which is better for sound quality?

http://www.ti.com/product/OPA2134 OR http://www.ti.com/product/OPA1642, the OPA1642 can be used fully diferential(balanced) to a studio monitor or amp, just like the OPA2134, but which has a better sound quality? the OPA1642 is in a Roland Mobile UA USB interface(https://www.roland.com/global/products/mobile_ua/) with the DAC AKM AK4414EQ, and the OPA2134 in the Emotiva DAC pre-amp XDA1(https://darko.audio/2011/08/emotiva-xda-1-dac/) with the DAC Analog devices AD1955.
