The issue you are going to have is that the very nature of the original recording and vinyl representation leaves it open to what could be conceived as a bad recording. Because a lot of the tracks are just a Moog without a dense mix, any crackles, rumble, artifacts can be easily heard. There is a lot of open space, it is very dynamic and frequency-wise there is barely anything going on above around 10khz (I actually rechecked this morning when I saw your request).
The 2005 rip you talk of is the version most people have on here and to be honest, the other rips I have heard of this LP have actually been worse because the owner had tried to clean up and remaster the album, and in my humble opinion, didn't do a good job. I have not seen those two versions in circulation in years. The 2005 version is not actually that bad considering the original material.
Hopefully, somebody on here has another version, but I think you will probably just get the 2005 version and if there is another version around, don't get your hopes up too high that it will be a great recording. Hopefully I am gloriously wrong lol
