I'll throw in my two cents regarding the 33rpm classic records set.
Led Zep I 200g - Phenomenal! What LZI should sound like. Lots of balls! I have a hard time believing the remaster would best this
Led Zep II 180g - Copy of the master tape was used but after hearing an RL Monarch, this issue is nothing to write home about. From what I read the remasters wins!
Led Zep III 200g - A little bright but very revealing and a great listen. You are either gonna love it or gonna hate it. I love it! Alot of reviews vary between this and the remaster
Led Zep IV - I have been satisfied with my UK plum so I have never bothered. Lots of fans of the 200g but from what I heard the bass has no presence.
HOTH - Satisfied with my UK Porky/Pecko but I have heard this one is disappointing
PG 200g - A little disappointed with this one. The volume on certain tracks would fluxuate on the copy I heard. Could of been a shit pressing
Presence 200g - The best sound you are gonna find for this masterpiece but the UK 1st press is great too along with a US Monarch. Well, let's see what Jimmy has to offer with the new remaster.
ITTOD 200g - Another beauty! Best pressing of the album but in my opinion, a Canadian first press is just as good and cheaper. Bring it on Jimmy!
Coda - No idea
