I wonder if ABC considered doing an updated version ?
There have been several official remastered release of the LP since. One (or some) of them are considered to have the best sound quality i think. Which one(s), i don’t remember, there have been so many re-issues (cd/digital) it became very confusing.
Personally i am totaly fine with this version, i am not an audiophile. But for the sake of the set being up to date and compete in sound quality with the official versions.
