SHM-SACD version I have, and this version of the same?Without seeing the SHM-SACD version you have, I'm not sure. Is the one that I posted just recently? If so, then yes, they are the same recording. I put this one in a separate thread only because it has additional material (Till Eulenspiegel, Don Juan, Seven Veils Dance) and would therefore not match the Zarathustra-only SACD's content in the other thread.
But the two Zarathustras are both the same Karajan/Berlin 1973 recording.
So you could conceivably download this album, delete the Zarathustra files, then go to the other thread and download the 2-channel SACD version of Zarathustra, put those files with this album, and you would then have this album's exact same content, except that you would have a hi-def Zarathustra.
Let me know if you still need anything cleared up.
