Hey, I was lucky enough to have been born in a time and a place where I could regularly buy decent BN, Prestige, Impulse, etc. vinyl for enough years before CDs were introduced to tell you that if you think that that stuff sounded better on CD than it did on the LPs, well, there's your "bullshit sentiment" right there! I'm not talking the rare first pressing either. I'm talking regular, store-grade LPs available all through the 70s. Pop albums, maybe not so much, especially as the decade wore on, but evn then, if you got a bad copy, you just kept exchanging until you got a good one. You could do that then...
There are no absolutes here, but I've held on to my LPs, all of 'em, and have no qualms about doing so. None whatsoever.
Of course, once digital recording came to the fore, all bets were off, because a whole lot of the early digital recordings sound like total crap. Nothing sounds real, especially pianos and drums (I've heard early digitally recorded piano and drum sounds that would be impossible to replicate in the natural world!). That's done a complete 180 now, but we're not talking about now.
The very first CD I had in my house was an Aretha Franklin Atlantic side of which I also had the LP. I did an A-B and the CD sounded so weak compared to the LP that I didn't know whether to laugh or to cry, that's how jacked-up the CD mastering was.
But it was clean! And easy!
