Without making this thread about dx3pro, I would say that at least on SINAD, there is likely no audible difference. Your peaks would have to be above 100 dB before there is even a theoretical gain. At least, that's my understanding
I do, however, think that there could be benefits to go to balanced outs of possible by your speakers. I have the Kali lp-6 v2 and I am considering getting this D0100. I think that Kali lp-6 v2 + D0100 could be about the absolute sweet spot for me. Sure, bigger speakers could yield more power and lower extensions and sure, some DACs are theoretical better but in daily use cases, I would guess that this setup would be more than sufficient for many people.
