So, although you didn’t state which Innuos model you have, at least the model you have can’t run Core.
Do you have more than one endpoint?
Curious as to what your chain is that an Innous streamer should make such a big difference. How were you streaming before? Did you ever post your chain here? -
Not trying to be snarky or singling you out. Please don’t take offense.
The OP asked how the how the Zenith MKIII was at running Core and, in spite of any protestations to the contrary, by the evidence of your own post, Zenith MKIII is not as competent as a lowly i3 NUC.
I suspect the Innous Statement isn’t much better since at 13,000 Euro it still uses an N4200 Pentium. By Roon’s own spec sheet that is not enough CPU.
I like the Innous products and especially the OS (Roon could take some pointers for ROCK OS), but they overstep when the say they can run Core.
