Another way to ask this question:
Roon’s RAAT moves audio asynchronously as per @brian here : RAAT and clock ownership
My Roon Core can only see my Asynchronous USB Dac (as seen in the signal path). It can’t see what’s happening along the way (ie going through my isochronous PS Audio LANRover over the network).
So, does the isochronous LANRover compromise RAAT’s asynchronous protocol and hence compromise my asynchronous USB DAC’s guaranteed uncorruped data?
Just looking for brief answers @brian without going too much into it, if it’s even possible to explain something like this simply 
Cheers in advance, Sean
