Easy there, sparky. The man was a musician, not the messiah. I happen to agree that the earlier stuff had a much more emotionally engaging rough sound compared to the more dolled up later stuff.
THe Robert Johnson sessions.
Anything with Charlie Parker 
The Lazy Cowgirls Tapping The Source. This is one of the best LPs of ALL time, but the sound quality is worse than shit. The Dictators 70s albums have been remastered on CD and 180 gram vinyl. I don’t know about the CDs, But the vinyl sounds awesome. If those records have sounded that good when they came out, The Dictators would have had the success they deserved.
Leave those Misfits albums alone though. Danzig already fucked them up enough by replacing guitar and bass on the original recordings.

Inky-, Raw Power was re-released a few years ago remixed by Iggy himself, and it’s the heavy metal album to end all heavy metal albums.
I agree with the Robert Johnson recordings - I wouldn’t want them to sound like modern blues, but I just wish they were totally clear (maybe something like the Johnny Cash American Recordings album).
I wish all the Velvet Underground live recordings had been done on better equipment - they’re almost all good, but they need a lot of imagination to get the full effect. I’d love a well recorded version of Sweet Sister Ray.
Remember, good bad production is way better than bad good production 
Goddamn, man! Those are two of my favorite bands, you certainly have good taste in music. I totally agree about EDVRE, the production is so bad, it’s nearly unlistenable. As for Godflesh, I gotta side with the ranting Hendrix fan. It’s the bad production that MAKES it such a classic!!
I’ll go along with a couple-three of the above, and take a sidetrip:
Billy Joel’s debut (solo) album Cold Spring Harbor
It’s not a particularly stunning album, but I’d like to hear the songs at the proper speed. Seems the master was recorded just a touch slow (making the album play a bit fast), and it sounds like he’s lightly hitting on helium throughout the whole thing.
Thanks chief. I now see the error of my ways - can I help you teach the misguided fools that used to graffito “Clapton is God”?
Pale Saints The Comforts of Madness the songwriting and performance on this album are amazing (just listen to Chris Cooper’s drumming), but it was mixed horribly and “muddy” is the best word for it.
UnuMondo
The Byrds’ * Doctor Byrds and Mister Hyde. * There’s some great, I even dare say classic, rock music on this album, but whoever did the mixing must have been tone deaf. Sounds muddy no matter how good your sound system is.
Actually, this “reprocessing” method consisted of turning down the treble on the left channel and turning down the bass on the right channel. You could occasionally get a passably good * faux * stereo sound with this method, but most of the time it just sounded lousy.
Bill Evans Sunday at the Village Vanguard and Waltz for Debby (also a live album recorded at the V.V. the same weekend) -
These two contain some of the most groundbreaking music I’ve ever heard. History is being made in this tiny, smoky club, and thankfully someone was there to record it. Through it all you can hear the club patrons clinking their forks, laughing at small talk, etc. Oblivious. Unbelievable.
On second thought, perhaps I wouldn’t have that cleaned up. It’s instructive that people often aren’t aware of the exact moment history is being made, and the gravity thereof. This is life.
I would, however, like to see several of the crappy studio pianos used by Bill Evans chopped up for firewood. Sometimes they are horrifically out of tune - even on some of the most classic early Evans albums, before he got - um - indiscriminate with his recordings. I can’t think why he put up with a studio piano being out of tune, ever.
Not an album, but a single: I wish “Good Vibrations” by the Beach Boys was recorded in true stereo.
David Gilmour’s self-titled first solo album. Its a great album, but the mix levels are so low that one can barely hear anything without cranking it up. They’ve done some correcting of this on the CD, but it still doesn’t have the clarity or volume it deserves.
My copy of Disraeli Gears sounded horrid. Talk about a shame.
Good call.
Peng! by Stereolab. Some of their best songs are on that album, but they are really poorly mixed and the sound is just too “thin”, the overdubs are particularly bad because they were a much smaller band at the time.
Billy Joel’s Glass Houses. Excellent Joel effort, but he spits all his “s” (how would you write the plural of “s”?).
This album is genrally overlooked despite having numerous hits:
“You May Be Right”
“It’s Still Rock & Roll To Me”
“Don’t Ask Me Why”
Most everything that has been recorded in the last couple of years…ever since it became trendy to compress the life of all recording in the mastering stage to try and make them sound “loud”. They wonder why sales are dropping.
“Spine of God” by Monster Magnet. All their later albums sucked, but SoG was great, except for the production value - when I played it for my old drummer, he asked ‘Is this a demo tape?’
