I've got the "Fifth and Ultimate Version" according to the liner notes from the FIM vinyl produced by Winston Ma. According to the notes, he first re-mastered JATP in 1997, in HDCD 24K gold format. When XRCD came out, he said it offered better sound, so he produced it in that and the HDCD version was discontinued. In 2000, when SACD was launched he decided to redo it in that format. This gave him the opportunity to enhance the 2nd disc of the album, which prior had been made using a copy rather than the original master tape. After securing the full set of the original master tapes, he produced it in Red Book, SACD stereo and SACD multichannel. In 2007, he used JVC's K2 HD 24-bit 100K Hz format to re do JATP and said it was better than the previous SACD version. In 2012, he re-mastered it for the fifth time, using UHD 32-Bit mastering to produce a Redbook format. Winston says to please compare this version with any previous version, that there is "no contest - in fact, it's not even close - between the previous versions and this new and ultimate version in the UHD format". He then used Michael Bishop and Doug Sax to produce the vinyl. I have the 33 1/3 rpm triple album version, though a limited quantity 45 rpm, single-sided version was also produced.
