Your Not-So-Obvious Best Fidelity LPs

Janis Ian 'At Seventeen'.

I really like "At Seventeen," and consider its good sound as a bonus.  Her "Breaking Silence" album is even better in recording quality, but I still prefer "At Seventeen."

More pop/rock albums with good sound:

Warren Zevon (self titled)

Chris Isaak "Heart Shaped World"

Thomas Dolby "Aliens Ate My Buick"

Kraftwerk "Electric Cafe"

Pink Floyd's "Dark Side of the Moon" is commonly cited as a great sounding album.  It has, to me anyway, great music and pretty good sound, but, it is not their best sounding album (there are also too many issues of the album to sort through, the one I like is a German quadriphonic version that I heard only playing in stereo, but it beat out the Mofi version and the original US release).  To me, "The Wall" is their best sounding album and "Wishing You are Here" is another great sounding album.

Paul Simon's "Graceland" is another often cited great sounding album, and I agree on the assessment.  

I know people have gone off the deep end criticizing MoFi One-Step records because they were made from digital masters.  I don't agree with the critics; every one of the One Steps I heard were good sounding regardless of the choice of masters.  

It’s fun getting an LP because you like the music and being really surprised how good it sounds.  

I found an original U.S. ‘Frisco Mabel Joy by Mickey Newbury for 25 cents at a thrift store about a decade ago.  
The sound quality almost seemed like a joke, i.e. “I can’t actually be hearing what I’m hearing right now.” I knew the music was tremendous, but the idea that the engineering/mastering would be so good seemed like a joke.  
One of those thrilling, “holy s**t!!” moments.

I got an original U.S. 12” single of “Cat People” by Giorgio Moroder / David Bowie years ago for peanuts. I didn’t listen to it, just bought it. Years later I had a very good music setup, for some reason decided to throw that 12” on and sat there amazed at what I was hearing.

I remember playing an original US pressing of Neil Young’s Harvest I had just bought (with the ‘fuzzy’ texture sleeve and the cool inserts, got it for real cheap) and going, “whoa! Didn’t expect this!” I remembered the CD I had as a teen (I wasn’t around in the vinyl days…I’m 41) as being unremarkable sonically. Not this puppy.  

Same thing with an original US Berlin by Lou Reed. Loved the CD as a teen.  
Got a cheap original vinyl copy in my 30s. Lou’s voice was this big, three-dimensional apparition, sitting right there in the center, felt like I could reach out and touch it, the instruments were big, rich, lush and grand and clear. Didn’t expect all that.

And Then Nothing Turned Itself Inside-Out by Yo La Tengo was one of my favorite albums in high school. I got an original vinyl pressing (this one was not cheap) a few years ago at Amoeba. I remembered the 2000 CD sounding alright. This, however, was really something.

Digging through miles of “Easy Listening” vinyl LPs at a record store, LPs that had been on this massive shelf in the back room for decades, inches of dust on them, (the kind you ‘taste’ while sorting through), I found a bunch of original ‘60s Sinatra LPs. In terms of sound quality, September of My Years (I was able to score at least one copy of both the mono and the stereo, for a grand total of some $2 or something) was stunning. The record store guys saw me a lot, so they were cool about giving me deals. I would go in there and they’d say, “hey, this came in and I thought of you, so I set it aside.” It was a bunch of original ‘50s & ‘60s-era Sinatra LPs. I came to find that I should never be surprised by the sound quality of those Capital & Reprise LPs.  
But that initial exposure to both the original mono and stereo copies of September of My Years was just blow-yer-hair-back great. The music, obviously speaks for itself. Incredible.  
There must not have been much of a market for those LPs, as those guys darn near gave them away. There was once an original ‘57 mono of In the Wee Small Hours on the shelf for some $8 or something. Pretty good condition, sounded real fine after a thorough cleaning via Audio Intelligent 3-part /16.5 vacuum machine.  
He even gave me a discount on the sticker because I one 1 or 2 other LPs in my stack.  
Went and saw on Discogs it goes for upwards of $200.

Mahler123 mentioned Joni Mitchell. 
I have early copies of all her LPs from ‘68-‘75 and they all sound great. I’m particularly impressed with the sound of The Hissing of Summer Lawns.

There are a lot more but I’ve gushed too much.

Sorry, one more: larryi mentioned those live Carnegie Hall Belafonte LPs.  
I have to concur.  
Also, Belafonte recorded the song “My Old Paint” in ‘63, and this vocal track is on my short list of “All-Time Best Sounding Vocal Tracks.”
