ultraRendu dropouts at DSD512 and 768kHz

I'm working on solving a problem, and not making the headway I'd like. 

I recently received an ultraRendu to use with Roon and HQPlayer as a network audio adaptor (NAA). I am having trouble with the music stuttering or dropping out, primarily at DSD512 and 768 kHz, which are the maximum specs for the ultraRendu. 

My setup currently is Apple M2 Ultra (Roon or HQPlayer) ---> (Gigabit Ethernet Switch (4 different types tried (both managed and unmanaged) ---> ultraRendu ----> Denafrips (Hermes DDC or Terminator 2). 

 

Has anyone dealt with this before, have any helpful insights, or can point to a forum where this problem is discuss in detail?

 

Thanks

I had an issue with my OpticalRendu and I resolved it by moving my ROON Core server so that it was directly attached to my router. Great thing about the Rendu's is that they do not need to be connected to the music server.

I used to have my ROON Core on the slow side of my home network, on the PowerLine adapter part (using in-wall copper lines). The bandwidth on that part of my network was not able to keep up with the hi-res data that I was streaming. The issue was 100% reproducible using George Harrison's All Things Must Pass stream. Specifically a part of a song where George whistles. My music always got garbled a bit during that passage.

When I moved the ROON Core to the faster side of my network, the garbled sound on that passage went away.
