It is from a CD rip yes, don't recall which version it is though.Oh my God someone else who has this. My copy is a Japanese CD reissue. Yours?
Is this QS encoded? Read about it in a book Jap Rock by Julian Cope.
And sounds like a good ol' QS encode to me pardner!
Artwork was made up from what the Quad LP (4K-20) would look like though -flyin' loose and fancy free just for fun
