Niemeijer, sorry, I never saw your post earlier. That was Carlos who you are quoting, not me. But I think Carlos was explaining that the AX24 can only receive a 2xDSD signal that is in the SDIF-3 format. So, you would need the SDIF-3 input card in the AX24 as well as a source that outputs a SDIF-3 2xDSD signal.
