Signal path is 'High quality' instead of 'Lossless'? (H190)

So if I want the best performance, I use my Node 2i again and don’t use the network feature of the H190? Somewhere in these threads I read that 105 is ‘golden’ for these amps, what does it mean, is it better with 105 than with 192 via my Node 2i?

Honestly I’m a bit disappointed and confused now, because I wanted an all-in-one solution.

PS: also with Coax I bypass the DAC of my Node 2i and the H190 DAC is used… Why can it handle 192 this way? Very confusing stuff.
