I don’t know what you use for a streamer, or what the rest of your equipment is, but might a bit perfect rip and the correct streamer compete with the K03XD? Not answering your question, but such a streamer also will improve what you do the most…stream.. Of course, I have no idea what the rest of your system looks like and based on the cost of the Esoteric, you probably have a killer streamer/server..
I understand that the above approach is more difficult with SACD in that there isn’t an easy way, that I know of, to rip SACD, but I suspect that high end streamers that cache the stream just might compete, but there might be some SACDs that are not readily available to stream.
BTW… The server/streamer that I have in mind would be the Aurender W20SE.
