Why do my rolling stones albums sound bad?

I'd opine that many Stones albums are of audiophile quality and some examples are Love You Live, Under Cover, Voodoo Lounge, A Bigger Bang.

I can only speak on the material from "Beggar's Banquet" through "Undercover", as I don't like their music outside of that range. My first RS album was "Emotional Rescue". In time I owned about 4 Atlantic distributed copies on the Rolling Stones records label, and all sounded muddy, especially the very first track, "Dance Pt.1". None of these were brande new sealed copies.
About 4 years ago, I found on Discogs a sealed copy and I quickly bought it. I think I paid about $25 for it. "Emotional Rescue " is not a highly prized album. The record was sealed, and it did not come with the poster (by now I had 3 of them in my collection). It was a Columbia pressing, as for a time, the Rolling Stones got a better deal with Columbia to release their albums, and some of them were re-pressed. While the label skimped on the poster, they delivered a much cleaner, sharper sound. This was like listening to the record for the first time. Mindful of not ruining it, I played it only once, and today it resides in my collection.
And, finally, the same can be said of "Black And Blue", another unloved, underrated album, but full of good songs. Not a single dud in my opinion. 
Last month I went to a record fair, and founf a sealed Atlantic pressing for $45. I got it for $37. I haven't opened it yet, but when I do, I hope I will be pleased with the following two things: (1) that the record will sound clean and sharp and (2) that the record is properly pressed CENTERED and not OFF_ CENTER, as I found on two copies I owned.   Even between Atlantic pressings, there is a difference as the record appears to have been remastered but with a duller sound. The catalog number is the same, but you can tell from the inner wax, that these were different stampers, and the copies did not sound alike. I kept the better sounding one and sold the other one in a bundle.

Get your Ya Ya's Out is so muddy at points on LP or CD or streaming as to be near unlistenable no matter HOW low you play it. As to whether Maggie's will deliver enough bottom end, I recommend a good subwoofer. As I sit here with my 30.7's driven by the NAD M22 and JL audio E-sub I've got plenty of tight, driven bass for anything. The problem is really the recordings. You may run into some pressing that manages to somehow interact better with your system than another but in the end what you hear is what they wanted. My preference would be for less mud, but that's just me.

Must be the era to some degree. I've been disappointed in general w/ Led Zeppelin LPs. It didn't bother me back in the day, but compared to other albums today they sound inferior. But the chemistry of their music in the studio is amazing.

Man,this quarantine must be getting to us...
8 year old thread. We listen to Stones albums(LP's) because it's the Stones, not the for the SQ.
R&R live albums are always a crap shoot. I don't however, hear the bass as "muddy" on my period press.
