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.

Do you know what package this comes in, how will you use/install that?

Hello everyone, I have the DAC Emotiva XDA-1 preamp with the DAC Analog Devices AD1955 and Burr Brown OPA-2134 op-amps, I want to update to the Burson Audio Play with the DAC: ESS Technology SABRE32 / ESS9018 and NE5532 X 3, NE554 X 2 op-amps, would it be a good update to the Burson Audio? thank you very much to all.
