Why would anyone want to isolate digital signals twice?For me the critical point here is if you buy this (Arce) then adding a DDC
Mumbo Jumbo, I guess they are aware that this kind of device will have limited market so it can`t be expensive. 384khz/24bit data is probably in limits of isolator chips used between circuits. Price for higher bandwidth rises fast, as cannot streamer without screen, lack of traditional digital inputs and no support for major streaming services.So Denafrips ARCE naa only support up to 384khz
