Hi, I did a little test-recording:
OB 24-bit via USB (Rytm) vs. UH-7000 24-bit 192kHz via balanced line cables (tried to get the same levels)
8 bar loop - 4 bars each - can you tell which is which?

Easy… 2nd 4 bars is the balanced line cables 
At least thats the one i prefer… first 4 bars sound a bit warmer but I can hear some additional harmonics at the end of each of last 4 bars…
Maybe am going crazy.
you are right! Was it really that easy for you? 
I think they are pretty close - find it hard to hear a real difference. maybe nuances… (tried DT-880, closed KNS-8400 and cheap monitors)
I guess that also means that OB rec quality is pretty good
Doesn’t soundcloud encode all uploads at 128kbs?lol
I think so, but as they would both be 128 kbs the sound differences would still be there.
Ok, fair points, so here is the original .wav file:
and in addition to that the same loop, recorded with X18, added at the end:
