Thanks. I really like Roon for its whole home Tidal + Local files integration. So I will keep it. But on my CXA80 system, which is attached to the TV, I only have CC tv and not CC audio, and they don't play that well together (there is delay, from 2 different products). So if I play to that system (actually my best one, with Definitive Tech Mythos ST) I don't try to also go to cast groups elsewhere in the home, and so my other part of my question still has me wondering: will I hear any difference between the CXN and the CC-TV, given that the DAC would be the same for both (the internal one to the CXA80)?
