Of course they should have used the session tapes, not later mixdowns.
That's a given. The part I don't get here is doing DA and AD conversion
just to use the analog mixer, if I understood that right. The resulting
192/24 signal has thus been unnecessarily converted twice already and
subjected to a bunch of old analog electronics. Also, I don't get the need
for a mono version derived from the same tapes, and personally, instead of
that I would much rather have had a three-track SACD version, which they
have precluded, but that's me.
Best,
