I’m not sure as I haven’t owned them,… There are differences but most likely negligible.
To be honest, the Steinberg UR44’s are fine. Sure there is better. The Twin X may be better, but a X6 would be much better, relatively. But more important,.. what improvement are you looking for?
Audio quality on the way in? line out? monitoring? I may have not got the answers, but I do have the questions for you
