I'm confused by the "remaster" tag on the new Practising Nature Oophoi CDR reissues. Some of them I thought had already been remastered. For example, "Mare Vaporum"--I have the CD edition called "Meditation" (on label Applaus) in which tapes were remastered by Karel Kourek around 2003-2004 (who remastered the other "Mare" discs which came out on CD on Nextera), but I notice there is a "2010 remaster" CDR of Mare Vaporum. In 2006, Umbra reissued "Celestial Geometries" as a remaster of the original album plus included an extra disc of unreleased pieces. Now there's a 2012 edition (two separate CDR's) of this set. Are they really remastered again, or is this just simply a reissue of the 2006 edition???
Can anyone comment on if it is worth replacing my Umbra discs. Is the sound quality significantly better?
