I suspect that the discrete masters are long gone and a decoded QS version would be all that is available. A couple of the Modern Harmonic/Sundazed reissues claim to be mixed down to stereo but I am wondering how they took out the QS information. I assume they used the LP master tapes which would most likely be QS encoded two track masters. I like the quality of other Sundazed titles in my collection so maybe the MH reissues are the way to go for Sun Ra fans.
I have all the MH titles and they do sound great!

But Sun Ra in surround sound and/or SACD......
