i haven't bought any remastered cds at all. in fact, i dont even buy cd's anymore. the loudness war has really ruined music on cds for me. as for the original question. a remastered album has to be done correct or else its literally a waste of time. if those Black Sabbath remasters sound like crap, then i will stick to the originals that i've been used to for the past 35 years.
some recent remasters i have picked up are the first 4 Sonic Youth full length albums
as much as Sister is kinda recorded in that lo-fi'ish kinda sound. it still sounds pretty good
i've only owned the cd versions of Confusion Is Next / Bad Moon Rising / Evol / Sister back in high school
of course i dont have them anymore as i unloaded my cd collection over the past 10-15 years
but the one that i couldn't believe my ears
is the half speed mastered remasters of the early Genesis albums with Peter Gabriel
i couldn't believe how clear they sounded. and i couldn't stop playing them the entire weekend i bought it. must've played each album at least 5 or 6 times. the clarity on them was just amazing and nice and clear. i didn't hear that stupid loudness in them at all. which i will admit, i dont own a top of the line stereo system, but for what it sounded like cranked up on my crappy system. it was a total experience. i manged to luck out and score this box set for only $130 (with tax) and it is so worth it.
but i find myself wondering. is the cd version just as good or better sounding?
i like the fact that my car has both cd and a tape deck in it so i taped every album on cassette and usually end up playing them the most in the car. espically on long drives.
as for the most recent remaster i got, is Ozzy's Diary Of A Madman (180 gram lp)
it sounds alright, but i dont have an original album to compare it to. it sounds alright, but i wouldn't say its in heavy rotation, but a good album to just throw on and do the dishes or cook dinner.
the last remastered album i did order is the first Shadowy Men On A Shadowy Planet - Savvy Show Stoppers LP (180 gram)
they are bringing out all 3 of their albums again, and can't wait to hear the first 1 (i believe they are being released 6 months apart) just glad i still hung on to those cd's still. as much of "Cargo Records" catalog seems to be long out of print. it's just too bad they didn't have the album when i saw them live a couple months ago.
i am very cautious about remastered albums, and it all comes down to paying good money for 180 gram albums and just end up getting a crappy version that i refuse to listen to (which i'm glad i saw that Nirvana's Nevermind was mention here as crappy sounding, so i will stay away (lol) from that one by all means.
oh yeah, another good one i really liked is Alice Cooper's School Out (on Friday Music 180 gram)
that one does sound really good
oh yeah, and Deep Purple's Machine Head (180 gram)
maybe i should just sit in front of my record collection with the laptop to avoid me adding more stuff to this list
