Ok understood, that is something which only RME can answer on a technical level.
I could only bring in another thought if you allow.
Ever thought of buying an UFX to get most flexibility and advantages also for recording? If you potentially want to improve in different areas, then this could be also an option, maybe not "cheap" but worth every penny.
I come from a Focusrite LS56 and switched to UFX with ARC. After that you have all you want and ever dreamt of. But all depends also a little which i/o's you really require or whether its maybe more beneficial for your use case to have the i/o's split across 2 devices.
If all shall be used around and under the control of your PC, then one recording interface which gives you "everything" would IMHO a good way to go and to improve in all areas (Quality, Flexibility, Features, Workflow).
UFX is fully standalone, has DuRec, AutoSet, you can save the Gain digitally, etc lots of improvements. More I wouldn't tell in this thread which is about BBF Pro, but I just wanted to give to you the idea of entirely "cleaning-up" and improve your whole setup with one device.
