Looking to upgrade from Xonar DG.

Greetings r/headphones. I am currently using Xonar DG along with DT 770 headphones. Love the sound but unfortunately the Xonar DG doesn't have RCA out so switching between speakers and headphones is becoming problematic.

I've seen reviews praising ODAC + O2 but neither of them have RCA out for hooking up powered speakers.

I want to switch between headphones and speakers with ease and my budget is 200$ give or take. From research I've stumbled across Audinst Hud MX1 and Audioengine D1. Both support 24 bit audio and have RCA out. Audinst seems to have an amp built in as well. Do any of you have experience with these units or suggestions for something else? Thanks.
