Sorry, I should have said, "never been released on SACD
*outside of Japan." Most of the Yes catalogue through
Big Generator has been put out on stereo SACD featuring atrocious mastering by Isao Kikuchi (see: the
High Vibration box set).
To be precise, Kikuchi seems to have mastered Yes albums twice.
The first time was circa the year 2000, for HDCD releases in minisleeve replicas. Two of those remasters,
Tales and
Relayer, when decoded, are still my go-to
listens for those albums. They sound excellent. That series included all of the 1970s album + Drama and 90125, and my memory is that for the rest of teh sereis, the mastering was 'OK' at best and 'not good' at worst. They got trashed on the usual audiophile sites for being compressed, but in fact, most of that 'compression' goes away if you decode the HDCD (because 'Peak Extend' was used). There is no obvious compression (waveform peaks) at all on the decoded
Tales and
Relayer. THe other slam was extrene re-EQ, which again I don't hear on those two albums (though his
Yessongs certainly has a heck of lot of re-EQing)
Later it appears Kikuchi re-remastered for the
High Vibration boxed set, which everyone seems to hate. I don't recall whether I or anyone ever verified this terrible mastering or not.
All those 2011 Warner hybrid multichannel SACDs were essentially format-swaps of previous DVD-As (including
Rumours,
The Nightfly, and
Machine Head).
Yes, it is just otherwise pointless catering to SACD-philes.
