If you get really obsessed - decades of listening and research, and thousands of dollars have yielded this for me (yes, I really have listened to this music and vinyl over and over):
Moodies -
Days/Passed - mediocre all around; UK original
Threshold/Dream - Nautilus and MoFi vinyl
Children's Children - MoFi is the best, but not great; all others are pretty bad (original recording is horrible)
Question - UK original
EGBDF - UK original
The recent SACD releases are better than any vinyl, unless you are a near-anal purist for the original mix. "Children" is a revelation.
Blood, Sweat, and Tears - MoFi and SuperDisc
Beatles - UK originals on ALL, with alternate choices of the German DMM of "The Beatles" (White Album) and the Japan Pro-Use of "Abbey Road."
The White LP is gritty; the DMM reduces grit, without being bright. "Abbey Road" Pro Use is wonderful.
(The MoFi pressing of the Beatles' lp's are quiet and sound good, but are NOT what the original mixes sound like.)
If you have unlimited funds the original mono "Please Please Me" with the gold lettering is the group's only recording that puts them in your room.
"McCartney" (first solo LP) on Japan red vinyl is stunningly good
... uh in terms of sound quality ;-)
Elton John -
For all LP's through "Yellow Brick Road" get the original UK pressings, as a rule. They are on the DJM label with virgin, dark translucent vinyl.
However - the DMM "Madman" is arguably better than first UK pressing, although it's hard to tell which is more accurate. The first Japanese pressing of "Elton John" is the only pressing of the LP that has a claim to sounding good, but getting a red vinyl copy is tough and $$$$$$. First Japanese pressing of "Captain Fantastic" is the best.
