Tux at Archphile has already started a unoffical MPD package with SACD/DVD-A ISO support.
Here is the link to the details:
Can we have this MPD SACD ISO support incorporated into OSMC?
An APP store add-on should also work.
OSMC would be the best HT all in one in that case.
Currently running a Pi 2, would be great if it works for it.
Thank s alot.
